Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
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.
4800 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.
2400 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.
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.
25 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.
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.
Glass Carbon 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
Magnet Structure
Defines the overall structure of the subwoofers magnet.
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
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.
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 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.
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.
2.75 cubic feet
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.
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.
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.
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.
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.
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.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

Get wit it or get lost

June 6, 2009

I did alot of shopping around before I purchased this sub and it was will worth the wait. If you go to orions website the have all the top rated subs versus the hcca. And hands down this thing is a monster. For the price the look it is sick. I got 1 in a tahoe with a hifonic BXI 1600 running at 2 ohm and i call my system aids/hiv cause its killing anybody with 1 sub and even 2. I went to a shop that sells JL and the guy was like man that thing slams real hard 1 in a ported box with a 5 fared cap I drove around for 4 hours on a trip beating this sub it never cut off. Maxxsonics is the shiznit 4real. JL,Kicker,MTx,its all in a name Hifonics are cheaper and slam hard im not even pushing it full power. and im setting off alarms like crazy.....

Simply amazing

May 11, 2011

I love these subs. I have two of these and they not only hit hard and sound clean but they destroy other subs such as the so loved Kicker L7's. If you don't get an amazing dB read from these then either rebuild your box or take it to someone because they will hit extremely hard. Just 2 of these in my 06 Mustang GT powered by 2 Hifonics Brutus BX-2200's with an extra battery and a 270amp alt and these things beat my friends 4 JL w3v3-4 subwoofers and were just as clean sounding. The only thing that sucks about these subs is that they require 2.5ft^3 of airspace in a ported box.

August 19, 2009

I bought this sub a couple months ago and i was back and forth with the decision of the orion HCCA and this sub, but since i was going with the transformers look in my truck i decided to go with hifonics since i have a history with maxxsonics products and these subs havent let me down yet.
i have these 2 subs hooked up to a lanzar opti 2000D @ .5 ohms. now i know you guys are thinking what the hell but yea i switched my wires out once because the melted through and upgraded to some stronger wires and now i cant wait to upgrade to 4 power acoustic 5500D amps and add 2 more olympus subs and hopefully i wont shatter my windows. LOL

SPL 100.05db is under rated listing

April 1, 2009

I bought a pair of Hifonics OLM2412's.

Each has Quad (4) X 2ohm voice coils rated at 2400w RMS, and 100.05db S/N ratio.

I installed them into my Dodge Grand Caravan into a 4ft X 4ft X 18inch ported custom fiberglass box. Installed my 5500w Hifonics amp and a 20 farad Cap. My lights do not dim ever. The rest of my system is the stock premium sound system CD/Cass/AM-FM unit and 6 speakers.

OMG!!!

I have an SPL testing unit that blacked out at 152db. It will not read high enough to accurately measure what these subs can do when powered properly.

I have them wired to 2ohm each then bridged onto the amp as 1ohm load.

You can not talk in my van, you can barely breath, and you need head gear to protect your ear drums. @ 6 foot away from outside the van we get a reading of 132db SPL.

I will not run the system with the windows up for fear of replacing all the glass on the van.

I think the Hifonics has grossly under rated these at 100.05db SPL. I think they are much much higher, and I only have 2 of them.

I am very pleased with my $2200.00 investment.

this is legit

August 1, 2009

this sub is absolute power just had one installed in a ported box in my 2008 honda accord 4 door got a 1200 wat sony amp and and absolute amp kit and a 3.5 farad capacitor. everything was purchased from this site except for the amp i had it. box-sub-amp kit-capacitor all purchased and installed yesterday. set off 5 car alarms on the same street with bass level at -4 and svc on low and volume 22. this is a definate headtruner and very underpriced. my friend bought 2 subs and box at $1300 and my this 1 12 in that 34.00 ported box whooped hit butt. he was pissed he is now ordering 2 of these to run and selling his old ones. I WOULD RECOMMED THIS TO ANYONE WHO HAS A LITTLE BIT TO SPEND.
