Infinity subwoofers have always distinguished themselves clearly from the competition. The Infinity SSI Kappa series subwoofers are no exception and fight on a playing field all their own. Right away the coated glass-fiber cone shows off an air of sophistication and style while offering incredible rigidity that minimizes distortion.

Once you get past the cultured exterior, the interior components uphold Infinities affinity for advanced technology. This Kappa sub utilizes a triple voice coil system which gives it the incredible ability to offer selectable impedance. Selectable Smart Impedance (SSI) technology allows this sub to run at 2 Ohms or 4 Ohms with the flick of a switch. This allows you to extract the most from your subwoofer amplifier in any situation. If you decide to add a subwoofer down the line, SSI makes it easy to reconfigure your entire system without buying different subwoofers or amplifiers.

The SSI Kappa subwoofers handle a remarkable amount of power and sound incredible in sealed or ported enclosures. If you want great sounding bass with unheard of wiring versatility, Infinity Kappa subs are technologically advanced enough to handle it.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Kappa (Infinity)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
1400 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.
350 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.
2 or 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).
23 - 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.
17.50 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.
Gold
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.
Coated Glass Fiber
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.
1.00 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.
1.00 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.
2.00 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.
2.00 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.
6-5/16"
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.
11-3/16"
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.

Couldn't be happier

November 24, 2011

I have owned this subwoofer for 4 months and I couldn't have been happier. I can't say anything negative about this subwoofer. There are many great thing about this subwoofer. 1. It works well in a compact box. I have it in a 1.0cu ft sealed Sonic sub box stuffed with polyfill. Unlike many car subwoofers, this one is actually optimized to work in reasonably small sealed boxes (1 to 1.5 cu ft). WinISD recommends 1.2cu ft when running in 4ohm mode and 1.7 cu ft in 2 ohm mode. I run it in 2ohm mode, in effectively a 1.25cu ft box (due to polyfill), with resulting qtc of about 0.76, which is almost perfect. 2. Good sensitivity and power handling. Don't worry if you have a modest amplifier. This subwoofer can still get very loud when running off a 250watt RMS power, much louder than is actually necessary IMO. However, should you want to play it a little too loud, I don't see why you could power it with 500w amplifier. Harman Kardon is being obviously modest with subs power rating. The xmax figure alone suggests that this Kappa should take up to around 500watts while still operating in its "SQ" range. 3. The cone looks great. 4. Low Inductance. Most subwoofers have such high inductance that their manufacturers do not even report it. This sub has Le of around 1.18mH which is considered much better than average. Low inductance is generally good for transient response and blending with the front stage. 4. Great sound. Let's finally get to the core of the review. This subwoofer plays very cleanly and transparently. What I hear is a very clean, robust bass with a good texture. It's good for practically any music genre. Midbass output is higher and cleaner than that of an average car sub, which makes blending with the fronts much easier. Don't be afraid to bump your crossover frequency a little higher. (I have mine at 70Hz, up from 60Hz with previous sub). I could go on to continue building a list of things that this subwoofer does correctly, however, I think it would be much easier to say that it does nothing wrong IMO. Based on what I have heard so far, most Harman Kardon (owner of JBL and Infinity) subwoofers are very good performers, and this subwoofer is a proof of it. I feel like I have been converted. Should I look for a higher end sub in future, once I become rich and famous, I will probably pick up a JBL WGTI from the same company.

smart subs for audiophile taste

March 26, 2011

I have 2 of these Kappas, each being driven with a JL Audio 500/1v2 high-damping amplifier. I have the impedance switch set to 4 ohms on each sub for better excursion control. Let me tell you this, these Kappas reproduce every range of bass like a pro... very detailed yet extremely hard hitting. I have them in a sealed, 1 cubic foot per-sub enclosure, and they handle every bit of the amps' power (gains set at two-thirds) using common sense with the volume control/ bass knob. If you want remarkably precise sound that can still rumble the car very well with enough power, these Kappa's will do the job for sure. The impedance switch is very nice. Make sure your enclosure cut-out diameter is large enough... the mounting diameter of these subs are 11 & 1/8 inches across. You can always sand out your box holes with 40-grit sandpaper to make them fit, but it's some work (and vacuuming dust). If you want superb sound, go with these in a sealed box, they would probably work fine in a ported setup also, but the average person with little experience with boxes who likes tight, accurate bass should be very happy with these Kappas in a sealed enclosure.

Just as good as JL w3v3's... and better for a smaller box

November 20, 2010

I have 2 of these remarkable subs in my Camaro. I have them set to 4 ohms, and I'm driving each sub with one JL Audio 500/1v2 amplifier... They handle the power very well, I have each JL amp set two-thirds of the way up. The sound quality is brilliant, and the bass is very deep sounding, even for the 1 cubic foot per side enclosure they are in. These sound just as good (and look way better) as the JL w3v3's- I've owned some before. The switchable impedance makes these subs very flexible... I'll probably own mine till I'm 40 yrs old! The only thing to pay attention to is their relatively large cut-out diameter... They won't fit into the same opening size as the Reference 12"s will (too big across)... So make sure your enclosure can accomodate these big boys. They are solid and weigh almost as much as Alpine Type R's, while being more effecient and clearer sounding. 5 stars on these!

awesome subs

September 23, 2010

I bought two of these subs six months ago and they have amazing sound quality! They are in a very small truck box underneath the back seat of a 2006 dodge ram. Total air space per sub is .65 cub inches. I was amazed at how low of a frequency they could reproduce in an enclosure that small! Throughout the whole frequency spectrum these subs are amazing no matter what kind of music you listen too. I am very pleased once again by the quality and design of Infinity. These subs are a great deal and you will enjoy the quality of their tonal reproduction from 28hz up!

April 4, 2014

I bought this trying to upgrade my old system. I wanted better sound, not more sound. The bass, the kicks, low end sounds sound like what they are, not just boomy bass. Its not as loud as my old subs but I went sealed this time instead of ported. Hits hard on high and low bass. Plus, looks freaking awesome. May not be as loud but it is so clear. Dont get me wrong, its still loud..... Btw, be careful with the Ohm selector switch, which is cool btw, I had it on 2 ohms and my amp was pushing 850 watts to it for weeks. It took it like a champ though. I WILL be getting one more eventually.....

This combined with the 1300a amp is very impressive for the money. I've had a lot of different setups and I regret everything I've bought in the past. This single 12 and cheap amp sounds better and hits almost as hard as my 2 type r 12's with a Hifonics colossus. I wish I would have bought this sooner.

I've got this in a sealed box and bridged to a Clarion giving it only 180w plus an EQ boost and it will shake the eyeballs out of your sockets. Integrates well with Polk component 6.5s. I'm thinking of building a HT sub using it as the driver.

Audiophile Bass

February 9, 2013

I used a pair of the Infinity Kappa 120.9W's in a home, high-end audio system. I put them in 3 Cu. Ft. sealed boxes and placed one in each corner of the audio room. The Apogee Divas are closer to the listening chair, so the sub-woofers are behind them. The bass is awesome. I have heard many high-end subs and these are as good or better than some of the expensive high-end subs. With a db or two of boost at the low end, these subs go down nicely to 20 Hz.

Amazing sub for the price

December 19, 2012

I originally had an Infinity 1262w reference sub and the voice coil separated one day. Rather than trying to get a refund or warranty work I decided to get an upgrade and go with the Kappa. I now wish I had gone with the Kappa in the beginning! The sound is amazing. My box is sealed for clean tight bass and this sub delivers. I don't care for people to hear me coming a mile away but this sub is incredibly loud inside my car. To the point that people who listen to it generally have to plug their ears. I am only putting about 300w into it but it can shake my entire car and still play cleanly without any boominess or muddy distorted sound. I don't always listen to music like rap or hip-hop, so when listening to classical music or country the bass is supremely clear and not overpowering. I couldn't ask for a better sub for the money!

Nice enough

August 23, 2012

In a Sonic Sub Box: 1H12-1.0 (Gray) with dynamat on the inside to get closer to the 1.0 cubic feet spec. Drilled through the connector plate and ran monster cable 10-gauage speaker wire straight from the amp to sub. Powered by Infinity Kappa Five (300-600W on the mono sub channel), running 4 gauge and the BOSS cap-20. Can make 2002 Monte Carlo SS rearview mirror fall off. I think I had it set at 320LP with the db gain set somewhere between 60 and 80hz (I think). A 160LP might be what its on now, I was having a problem with my amp cuttin out, so I reduced the high frequencies from the deck too and the system can run at max volume now. The 400hz max range was kinda much to believe anyway (from speaker or amp@320). Once I get the candy amp rack made I think I'll pick up Infinity's other sub amp and give this thing the power it wants. Great deal for the price, lets you get the extended warranty option. Decent look and VERY durable, but won't look pretty after it shows you it is durable (the shimmer wears off).

Nice sound quality

July 1, 2012

I'm 44 years old and this is my first sub... This being said, I have always been a music enthusiast, and I'm very hard to please, I need a good sound quality system, and this sub was exactly what I was looking for! I changed everything in my car, radio, front and back speakers, and put a nice amplifier to go with it, the only thing missing was bass... After going over mountains or reviews, I finally decided to go with Infinity, I bought one of these, that I put in a sealed box, WOW this sub makes my car shake to the core! Incredible bass in my car, but only in the car, I did not want the bass to overwhelm my vocal, and this sub blends perfectly with the front stage, I threw everything at it, Pop, Rock, Metal, Techno Bass, even Classical! It reproduces every note to perfection, bass sound like bass, drums sounds like drums. I tried the sub a both impedance's, first a 4Ω, then at 2Ω, my amplifier sends 300w at 4Ω and 500w at 2Ω, worked perfectly at 2Ω but was a little to much for my taste so I put it back at 4Ω. all in all this is a very nice peace of technology, and the price is respectable compared to other SQ subs out there, and I highly recommend this product. If you are a Hip Hop fan, one will not be enough for you, two 10" or two 12" will shed the rust from your car in no time flat...

Excellent Sub

April 28, 2012

I wanted to add some low frequencies to my X5 which did not seem to play below 100 hz. After a lot of research, I selected this sub and hooked it up to a JBL GTO3501 mono amplifier. Could not be happier. I wasn't looking for kick *ss bass but rather fill the cabin with low bass that I can feel. This setup rocks. It will kick if you want it too but what I like best is the flexibility it has to sound excellent with all kind of music. It took some time to properly tune the amp and well worth it.

Had 2 in 2 sealed 1.2cf boxes they sounded good about 4 months and they tore all the way around. The fiberglass cone has a rough edge where it is glued to the rubber surround and cut the rubber. I tried to glue them but never sounded right. It's too bad they just didn't smooth the edge of the cone before gluing. I exchanged them for power caustic mofo that don't sound as good but much stronger. Do not use stated power cut in 1/2 for vented box keep ur warranty and packaging.
