Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Brutus (Hifonics)
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.
1200 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.
600 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.
Dual
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
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.
15 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.

Square
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
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.
1.25 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.
1.25 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.
1.5 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.
3.5 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.
6-1/2"
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.
11-1/8"
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.

mediocre at best

March 6, 2012

Sure, they sound good for awhile but I don't think I would recommend these. I purchased two along with the box and matching hifonics brz1200.1 and the products were defective. I will add Sonic handled the situation very well, and is taking the products back and we are working on different merchandise. I will also add that these subs did sound ok for awhile but didn't last long at all.

November 29, 2011

These subs are great! I have 2 of these and it rocks my jeep. I couldnt be any happier. They hit as hard if not harder than the Kicker square series. They beat the price defenitely and i have had mine for around a year and still are performing at top potential.

they blow, literaly

November 26, 2011

So I got a pair of these, they worked fine at first, however, after a few days one went defective and had to be returned, Sonic handled the exchange perfectly. So I got the replacement sub, they worked fine for a month, then one day out of the blue they blew, both of them. Mind you they weren't even hitting that hard at the time, half power. Everything was wired fine in the install. So my only conclusion is that these subs are not good quality like a lot of things from Hifonics.

October 18, 2011

I got 2 of them put in the other day. One of them sounded fine but the other was letting in static and it sounded very distorted. The installer tried everything to see if it was a prob with the wiring, amp, etc. but it turned out to be the speaker. So I had to send that one back.

LOUD

October 13, 2011

I have two of these bad boys in a Mitsubishi Eclipse, wired to a 1600 watt Boss Phantom amp at 2 ohms, in a sealed box that I built. Before I had them in my Eclipse, they were in my room and would shake things off the walls in my sister's room across the hall. Haha, I broke a lot of her stuff. Now in my car, they are wayyyy louder with the smaller airspace. My rearview mirror is pretty much useless, and I don't even like turning them up all the way because its just uncomfortable. These subs are well beyond my expectations, and a great value if you know what you're doing. They take the extra power like champs, and look great too. A lot of people have never seen square subs before, and are amazed that my 12's are so damn loud. My 12's are way louder than most of the kids' in my school parking lot, and my friend with two 15 inch Soundstreams finally has some competition. They hit the lows like you wouldn't believe, and sound GREAT when I play dubstep too. The only bad thing I have to say about this sub is that cutting a square hole with round corners and no template to go off of is kinda hard. But thats not the sub's fault. I was planning on upgrading to two RE Audio 15's, but I don't think that will be necessary. These satisfy the needs of even the biggest basshead.

Great Sub

September 20, 2011

Had 2 of these powered by a power acoustic amp. Thought the subs were bad since they didnt hit some notes like round subs did. BUT, later found out the amp was just a POS. If interested in Square subs, be aware of the sound frequencies squares give out compared to circles. and make sure to get a GOOD amp to power them.

really nice

June 19, 2010

I would recommend this sub to anyone who wants good subs at a good price. They sound great hooked up to 1800 power acoustics amp in a custom box. The only down side is that there was no template to trace to cut the hole for the speaker for the box. But other than that its a great deal.

overpower to easy

April 21, 2014

Wore them in for about 2 weeks. I turned my be.2500 d class to about 1/3 of power at 2 ohms and smoked them at about 500 watts rms a piece. The subs where far under there extension range and where barely moving. wiring and everything was all good. Also used my audiobahn 1200 watt mono at 1/6 power and cooked the amp till it shorted only playing for about 30 min. They hit hard for the price but i wouldn't recommend them.

hits

March 22, 2013

I have two of these in a ported box with a hifonics amp pushing 1400 watts rms. they hit so hard!!!!! It feels like your in an earthquake. They eat power. I have a 20 farad capacitor hooked up to my amp. And I wired everything with 4 gauge wire so the power is transferred, but at sometimes even my capacitor can't handle the load and my dash lights start to dim. I love these!!!!!!!

Damn Good Subs

March 20, 2012

I have two of these in my Isuzu i-280 in two separate ported boxes on a Boss 2500 Chaos series amp at 1 ohm at about 700watts apiece and these things slam. They are so loud I set off a car alarm across the road. Seriously great subs. Cheap price. If you are reading this, buy these now. They are great, love Hifonics and on a side note they are beautiful subs.

THE BEST SUB EVER MADE NO MATTER WHAT PRICE

March 15, 2012

Okay here it is. I have 4 of these brutus subs in my blazer powered by a 10,000 watts maxxsonics maxximus amp and its not over rated like all this lanzar and power aukostic junk. Each sub holds up well with 2500 watts going to each They may need more power but ill get to that later. THESE SUBS KILL ANY JL OR KICKER. My truck took home first place with 175 bd at the show and even hit so hard that I had to replace a cracked manifold on my engine. MAKE SURE YOU GOT ATLEAST 1500 WATTS RMS A PIECE or dont waste your time. Enjoy greatness.

March 6, 2012

I have owned several subs, this being one of them and I can honestly say this is an excellent sub. It was loud but lacking on lows. I bought two of the round versions and they really hit the lows great. But if your looking for highs and mids pay the extra for this bad boy.

hifonic 12" square sub

March 2, 2012

It's a ground shaker with the proper amp and set up, in my fullsize 88 blazer, cranked up high it will give you blurred vision. Voice isnt as strong as i was hoping, but for the price. WELL WORTH IT!!! It's been running at max now for about 9 months and it still hits like it did right out of the box.

January 10, 2012

I bought two of these and put them in my truck hooked up to a hifonics brutus 1700 watt amp wired down to two ohms so they rms at exactly 1200 watts. These subs sound really good and for the price they are a great deal. I would recommend them to anyone working on a budget but still wants the most bang for your buck.
