Extended Excursion NBR Surround

A strong and flexible heat resistant compound, nitrile butadiene rubber is used widely in automotive applications. Gorilla woofers utilize an extended excursion NBR surround for it's strength and flexible properties during extreme movement.

Overcast Stitched Cone Assembly

The surrounds of Gorilla woofers are double overcast stitched directly to the IMPP cone surface. In addition to superior adhesives, overcast stitching improves the conventional bond between cone and surround.

100% OFC 4-Layer Voice Coil

Gorilla woofers use generous 1.50" long, 2.5" diameter 100% OFC Copper voice coils. A vented Aluminum former extract and dissipate any heat build-up, resulting in improved power handling.

Back Plate & T-Yoke Venting

Heat build-up is a leading cause of catastrophic woofer failure. Venting built into the T-Yoke, back plate, and voice coil extract and dissapate heat, ensuring Gorilla woofers keep their cool.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Gorilla
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.
2500 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.
2 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2.50"
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".
84.2 dB
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.
Black
Red
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.
Injection Molded Polypropylene (IMPP)
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.
Nitrile Butadiene Rubber (NBR)
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Double Stacked
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
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.50 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.25 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.
6.25"

These Subs Hit

November 23, 2014

I have had W7's and Power Series and these subs hit just as hard as one 12W7 and are equivalent to Fosgate Power Series sub. For the price get them!

May 15, 2015

For the price u can't beat these speakers. I ordered 2 of these with the boss 5000 phantom series amp and it beats to death. And honestly the amp isn't doing these subs justice at all. They r in a vented box tuned to 36 htz and all of my friends can't believe how hard and clear they hit. I'm gonna throw some higher cleaner wattage to them to see what they really do. But for the price these r definitely a great buy. But do ur cut hole 11 inches exact and the sub fits perfect

I bought the spl sub from tool king and then I bought three more from sonic and I have to say that these subs hit hard like the vcw and I found out why heres the real proof that I found out foam hits hard on a subwoofer don't get me wrong on that but it also will start to crack with in a year or less when it is put in heave heat it will peel crack and distort now rubber will not do so it has a longer life span and now heres a trick of the trade that I do with all my subs now if you put the sub out of the box next to your ear and use you hand and tap the surround on the sub the bass will be herd and you will hear the difference on it all now as for the spl subs they hit I mean it hard and I am getting the ten inch one soon else where because sonic dose not have it for some reason but I will get back on that with it when I get three of them

SPL 12in Sub Gorilla Series

November 19, 2015

I love this sub. I originally had a cheap $20 10in sub that claimed 500 RMS. But I doubt it, anyways it started to distort under little power and it had blown out in under a six weeks. So I came here and found this sub that is rated at 600 RMS, and have had nothing but good experiences with Sonic Electronix. My amp puts out the equal amount of watts, so i don't even have the full 600 watts' potential (I'm not specifically sure how much continuous watts are powering it, I just tuned it by ear) . The system is in my dad's van, but when ever I get to drive it to school I have a smile on my face. Oh, and for its price it is even a better deal.

Excellent SQ!!

October 11, 2015

Surprisingly this subwoofer hits every note with superb clarity and power handling, just as long as you don't push more than 650w rms, even though the manufacturers website says it'll handle 1200w rms!! (not to mention there's a big "1200w RMS" sticker the the back of subwoofer it self). So be careful wire it correctly and set your gain and bass boost properly and you will definitely not be disappointed with sound quality of this subwoofer.

Cons: *Does not come with and screws *Fauls RMS handling

I was running a pioneer D9601 amp in one ohm in a sealed 1.5 cubic feet box. This sub blew in two weeks' time. Shouldn't this sub be able to handle 2400 watts? If not, what 12 in sub will run in one ohm and handle 2400 watts without breaking the bank?
ken s on Sep 13, 2015
Best Answer: I know this sounds boring but you should've wired that setup at 4 Ohms 500w. It would still pound pretty good and last forever. SQ of an amp is also way better at 4 ohm than 1 ohm because it's a walk in the park. Peak watts are just marketing hype. RMS is all that matters and this speaker handles about 600w RMS. Send double that and it the speaker blows up. Maybe try a Power Acoustik MOFO, 1500RMS.
