To Infinity, and Beyond Your Normal Woofer

Don’t let this 8 inch Infinity Reference subwoofer fool you; it has no problems pumping out deep, clean bass when you’re tight on space. At 1000 watts of peak power, it takes the heat without stepping out of the kitchen. All of this without sacrificing sound quality or cutting sensitivity.

Infinity’s product quality and excellence stem from their passion for music. This fact is evident in each of their lines, with no exception to their Reference Series subwoofers. Whether you listen to rock, hip-hop, jazz, country or anything else, these woofers will shine through with every note. High-gloss polypropylene woofer cone is lightweight which assures maximum efficiency which produces high output with modest amplifier power. This in no way means the Reference woofers don’t have a sound quality side, far from it. Sound quality is the name of Infinity’s game, and every beat will be smooth, crisp, and hard hitting. The large-roll rubber surround absorbs distortions that travel through the cone, ensuring clean bass response. Vented polepieces help cool the motor structure which allows for an increase in power handling. Engineering at Infinity is state-of-the-art and a great deal of computer aided design software is used to devise their products. This commitment shows in all of their product lines, and with such a good reference, it’s a no brainer.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Reference (Infinity)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
1000 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
250 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Single
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
30 - 400 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
91 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
13 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Silver
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Polypropylene
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
.35 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
.35 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
.6 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
.6 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
5-3/16"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
7-5/16"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
29.6 Hz
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
15.23 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
.45
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
.483
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
3.3 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.

Blown away yet again.

August 13, 2011

My buddy is running four of these in a 3 cu ft sealed box wired at 1 ohm to a hifonics txi750 to break them in. In a 2003 Saturn Vue.

Man these sound cleann~

They're extremely punchy and accurate in the sealed setup crossed over with the fronts so well, you can't tell where they roll off -- exactly how it should be. From outside his car, his his hatch doesn't rattle at all, but from inside his car, the bass is powerful enough to move my shirt about a 1/2 inch. These are definitely louder than my MTX 9515 despite being a hell of a lot cleaner.

He's ordering 3" aeros and tuning the box to 34 hz and getting a Soundstream TX1.2000 feeding each sub ~400+rms after box rise.

I'll post an update on how this setup sounds. He's also contemplating running 8 of them off that same amp.

These are the best 8's ive ever herd. I have them in prefabricated 1.40 cu ft box tuned @ 34hz in my minivan and wows anybody who hears it. not only does it have ACCURATE sound reproduction but they hit low and clean. The box can be found at mobilesoundworks.com. People thought i had my SA-12 by Sundown in there lol. They've been receiving about 600 rms daily with abuse for about 3 months now, i love them!

I have just one in a ported subwoofer bass tube and it hits pretty hard, it honestly hits harder than my 10''. im getting the infinity reference 12's soon and will be keeping this 8 in my car aswell. im pushing 500 watts into it at 4 ohms and it handles it with ease. it doesn't have and distortion and this subwoofer, for an 8'' woofer has a HUGE excursion. I love this woofer, its great for a little 8'' and I would recommend it to anyone.

Awesome Sub!!!

January 29, 2014

I purchased this sub for a footwell project in my miata. It's powered by a Rockford Fosgate 351s amp getting a lil over 350 watts rms. And Wow, not even broken in and it sounds amazing. The sub is mounted in a sealed box slightly under what it calls for. I listen to all types of music and this sub plays it all. Fills the entire car full of bass, which was difficult for a convertible. I highly recommend this sub!!!

The best 8" sub made

August 16, 2011

I have 2 of these in a 2005 F150 crew cab. Im running them each on 300 watts of old school alpine v12 power... all i can say is amazing sound. They handle everything i throw at them and ask for more. If you are looking for a sub this size, there is non better.

Clean to a whole new level.

July 31, 2011

I hooked up two of these along-side an MTX 9500 15". These were hooked to a Rockford Fosgate r1000 giving each ~550 watts. (only because my friend let me borrow his before he gets two more)

Upon adding these, all the mid-bass my 15 couldn't reproduce, is back.
These subs alone sound cleaner and deeper than my 15 (Not anywhere near the spl, silly) but the three of them really shine because they just don't have the low extension like a 15. After adding them, I definitely feel cabin-pressure I didn't have before. In the trunk of a fully-deadened 2002 grand prix (oh and what difference sound proofing makes)

HUGE HUGE HUGE output from these 8's. More than any 8 I've ever heard. Definitely comparable to two CVR 12s in SPL with a HUGE improvement in sound quality.

I've never gotten good results from mixing woofers, ever, but in this case, it sounds clean and articulate, and accurate at low levels.

Someone looking to just add near-perfect bass without rattling their car should look into running these babies UNDER their RMS cause the output from one is just too much if THAT'S the sound you're going for.

Thinking about running 8 tuned at 29 hz.

Infinity 860W, I love you!

January 16, 2010

I'ye had an 860W for about 6 month now and I love this subwoofer! It's in a custom calculated sealed box and it makes wonders in my little hatchback... I only have 3.5'' component in the front (and no rear speakers) so it's low-passed at about 180-200Hz and it kicks the mid-bass as well as the lows like a premium machine!!! Very impressive! I'm thinking of buying an other one an put them on a 500w/rms amp to up the scale on the SPL side... Recommend this sub to anyone with a small cabin (Any hatchback, pick-up...)

Best sounding subs I have ever owned

October 20, 2012

These subs are the cleanest things I have ever heard and they go deep for 8's. I have 4 of them in a sealed box I made myself. I started with 3 of them but it was not quite powerful enough for me, but 4 are incredible. Inside of my car the music is intense but you can hardly here anything outside of the car. The only problems I have found with these subs is they have the cheap wire connections, and that they did poorly on gluing the rubber part of the woofer to the frame. I had 3 of 4 of them start to come apart from the frame, but it was an easy fix. I would recommend anyone that is looking for clean sounding bass to purchase these, and as always Sonic is #1 in my book.

One small wonder

November 29, 2010

I would say I'm a somewhat savvy audiophile. I prefer smaller subs because I feel they sound better. Its also nice that they take up less space. I wasnt expecting too much from these guys (I bought two and wired them into two ohms) and was VERY impressed with their quality and power. They are very deceiving in regards to size and specs. Stick a well powered amp behind these puppies and they will sing. Btw, as usual Sonic had a superb value and selling price.

Sweet little sub

January 28, 2015

Swapped out an REXv2 for this because that sub couldn't take take the 250 watts my Kicker IX 500.4 puts out in bridged mode. Thankfully this Infinity handles that power level just fine, in fact it seems like it could take even a little more juice (400?)

The Infinity is not the loudest thing, don't let the high sensitivity fool you... based on other speakers I've used I'd say its more like 87 dB. Currently I've got it in a slightly oversized sealed box so that might be limiting its volume potential. Big box = deeper bass but less volume. For an 8" it gets pretty low and smooth, maybe a touch better then my old Kicker L5 8" with the same power & similar box. This is really well built sub with a big surround, double magnets, rubber cover and vent pole. I know it kicks much harder / moves further then the REXv2 because I had to remount my grill cover because the 860W surround was hitting it on deep bass notes! The only downside is the cheap spade style connectors.

I've got Infinity Reference components for my mids and highs in both my 350Z and Dodge Dakota so I know they are a good line of products.

best subs ive ever had.....

September 1, 2014

Running two of these in a 1.4 cu ft slot ported enclousure tuned @ 34hz and wow, it's sounds amazing. Been doing car audio for almost 10 years now and have had alot of competition gear as well as SQ - from JL to DD audio. Decided to grab a pair of these 8's since i was so happy from the 12 and 10" version. The response on Rock and Country is DEAD ON perfect. LOUD! Hip-hop and Decaf (slowed and bassboosted) Dubstep slams! Depending on your box (mines a starndard L-port) you'll be rocking hard. Running off a JL 500/1v2 im upgrading to a 1K JBL amp. Keep in mind i could fit 2 15's but choose to run these.

"Meister Petz" by the Peace Orchestra was smooth and low. "Hot Like Sauce" by Pretty Lights pounded like no other 8" sub I have ever heard. Im impressed.
This is not new territory to me. I have been building car audio systems for years and wanted something that made good use out of the space in my Hemi Grand Cherokee. I bought two of these and dropped them flush with grills into the back what doubles as a utility box with a slide out drawer. They are very boomy and tight in a sealed box.

Nothing beats these for the $. Harman products never disappoint me.

Great performing 8!!

September 22, 2010

I have owned this for 2 months and i love it. It reproduces bass like no other 8 sounds like a pair of 12s!! It makes the best of the space that it occupies. I'm using it in a vented wedge box, and it hides well in my car. I recommend this sub to anyone who wants very clean, clear sound.

these subs hit hard and lowww......................................... i have them in a 1.4 cubic foot box tuned at 34hz. you'd think have a really nice 15 in a huge box back there. theyre sq and response is quick and tight but the low end is still extremely beefy. im powering it with a Crossfire C5 1k amp 500+ watts @ 2ohms

Very Impressed!

September 17, 2013

My 6x9s burned up and I wanted a little more bass, so I actually mounted two of these bad boys in the rear deck of my Olds Intrigue in a free air setup. They aren't designed for this, but they still sound amazing. Even though I have to be careful about pushing them too hard, they still fill the car with rich deep, mirror vibrating bass, which is exactly what I was hoping for. Wouldn't hesitate to do it again.

Bang for Buck is HUGE!

January 6, 2013

I had a 12" shallow mount in the back of my wifes Nissan XTERRA is her Cargo Area. it was side-firing and wedged in a corner. Even so, everytime I looked back there she always had something bumped up against the sub or very near to it, so I just knew she was eventually gonna mess it up. Soo... I opted for this 8" 860W Ref and put it in a long and narrow 1 cu ft with a 3" Flared Port kit tuned to 32Hz. To test run it I hooked this 4Ohm setup up to my amp which is usually pumping 600 W into 2 Ohms. So 300 W @ 4 Ohms. Didn't adjust the gains or anything. I didn't try going up as high I as could yet and already it was really good compared to my usual Alpine Type-R 12" that's back there everday. The spider and surround feel quite stiff! Interestingly the frame of this sub is some type of spun-cast fiber material. Probably cheaper to produce, and definitely rigid enough for the job. With the amount of output I got from just this one. I'd be real interested to see what two of these together would do given same cu ft and same port cofiguration! I feel pretty certain it would out-perform the single 12" Type-R ported and for less money too! I'm going to knock a point off "Design" only because they're using standard spades instead of spring-loadeds.

Great Value! Great Sound!

April 28, 2011

Bought these subs for my 2009 G8 to install into the rear deck in place of the stock 8"s. First off the subwoofers sound amazing, they hit almost as good as my old 12"s subs did. Subs were great. However any one considering putting these in a G8 on the rear deck lid, don't do it. Installed the subs in the 8" factory spots, turned them on and it rattled the sh*t out of everything that was conected to the rear deck. So i spent 2 hours putting foam around everything to get rid of the rattles. Finally put everything back together and sat down to actually listen to the setup when i realised it sounds like sh*t. The bass response in the "free air" setup could not keep up. Still rattled a bit. Overall could not even come close to having a box setup. Im taking them out putting the factory 8"s back in and buying 2 12" in a box. To sum it all up Great subs but dont put them in the rear deck of a G8.

Great sub

March 20, 2011

Bought to upgrade 8" sub. Good sub. Needs a lot of power which I did not have in amp I was using.

Pro: Good sounding. Easy to install in sealed box. It needs a lot of power so be ready to buy a good amp. With the right power it will stay up with a lot of 10".
Con: Power hungry. I did not have a powerful amp.

SQ sub

January 28, 2011

Got this 8" to replace RE Audio 8". Gave to a friend for his car because I wanted more SQ than thump. Running off RF mono amp and sounds GREAT!!! I want SQ to compliment Hertz MLK 165 in front & CDT M6 braxials in rear. Running off 4 ch. US Amp. It is amazing that this sounds so good and thought I might have to go up to 10". No way, it is exactly what I needed.

Infinity 8" Sub

June 10, 2013

Great tight accurate bass from this 8" Infinity Reference. It's powered by the Kenwood KAC-7005PS 5 channel amp also purchased from Sonic. It fits perfectly into my custom made 8" "Lukebox" which is designed for fitment into e30's. Not overpowering sound but tight and accurate bass.

suprising

December 21, 2012

had this hooked up just to mess around with, hooked up to a hifi 100 watt class d amp and it suprised the heck out of me, i had it in an old pioneer bass tube and it hit pretty hard, going to hook it up in my dads truck for xmas and i know he'll be pleased, the bass in this 8" isint thundering like you would get from 12"s but it provides a tight punchy bass and for an 8" it goes pretty low, for the price it's a really great sub and if you have a tight budget or not very much space i recommend this sub! thanks sonic

Bought these subs to replace 8" drive drivers on some blown auDio bookshelf speakers. These subs are clean sounding and have a nice thump to them. Yes I have a pa amp that is 4 ohm stable and feeds these subs plenty. For the price, seems like I stole them. :)

Great for midbass, struggles to get really low

August 28, 2014

But in all fairness, most 8" subwoofers will struggle to get to extremely low frequencies. My ear is telling me I'm missing out from 45hz down, but for alternative/rock and midbass these little subs make a hard sell. They sound extremely clean, very controlled, take their rated power very well in a sealed enclosure. They are a single 4 ohm voice coil in a market full of dual voice coil subs (fewer options for wiring/ohm loads) but if you plan ahead for that they work very nicely.

Nice little sub

July 13, 2013

As someone who needed a decent 8" sub because of space constraints, this fits the bill. You can go with Sundown if you want truly incredible bass per size but this is a much better choice for those trying to stay within a budget. This subwoofer delivers generally satisfying bottom end to your music but it won't give you a huge back massage. Know what you're ordering and what to expect. It is probably better than any other subwoofer in its price range.

can i use these as replacement speakers in my slk 350 roadster? I need an 8" speaker and I can not find them anywhere. I have 2 3" tweeters in the door as well. I took the door apart and I found a plastic housing that holds the 8 " blown speaker and 1 3" tweeter
christy p on Sep 10, 2014
Best Answer: You may want to look into another 8" woofer since this is a power hungry sub that will not produce UNLESS you have at least 200W of raw power. Also, The depth on this speakers make them difficult to be used as replacements for any factory sub. Before ordering, you may want to measure the depth of your original speaker and compare it to this one. Also, you would want to also measure the max depth of the area where the original speaker is placed. Overall, this is an excellent speaker, but only if you could fit the criteria of its demands, which are having the correct area for mounting, and providing the necessary power that's required. I hope this helps.

Best Answer: This amplifier will provide plenty of power to the single 8 inch Infinity sub-woofer. The sub only needs 250W RMS . That rating is assuming you will be placing it a sealed enclosure. Any other enclosure will reduce the amount of power the subwoofer will consume. I am currently running two REF860W in parallel (~2Ohm Impedance) in a sealed enclosure. I am using a JBL GTO-501EZ amplifier that is providing 500W RMS total to both subs and it sounds GREAT!!!!! You should have no problem using this Lanzar amplifier with two subs. If you are going to only use 1 sub, turn down the power/gain to half way to protect the subwoofer.

I want to upgrade my amp can you run 300 watts RMS into this subwoofer?
Opus H on Feb 6, 2015
Best Answer: Hey, I'm a happy owner of 2 of these guys and I'm not guaranteeing it, but I think you'd b definitly fine running 300 watts. You should generally run between 75-110% of rms, but I don't doubt this bad boys could handle 500 watts. Id say go for it.
