Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Terminator (MTX)
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.
400 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.
200 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
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
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".
87 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
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
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
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
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.
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.
2.0 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.
2.0 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.
5-1/2"
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.
11-1/16"
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.
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.

The best buy in car audio.

November 23, 2011

This speaker is one of the best subwoofers ever made. I wont quote spl's or power handling statistics or any other such specification. I will point to the fact that this this speaker has remain virtually unchanged for 25, yes, twenty five years. In fact, I bought my first terminators in 1989. I have purchased at least 20 of these subs from 8-18 inches. The woofer has a natural tone and can accurately reproduce a wide range of bass frequencies. And yes, they can pound out 35Hz notes all day long. You can get maximum spl at around 200 watts rms, but even at 100 watts you can still pound the pavement, so you wont need a huge amp. Box size is very important for this sub. It is good for both ported and sealed boxes, as well as bandpass applications.
The only drawback is that the box size required is larger than a lot of speakers on the market. But in today's economy, this is the best value for your hard earned buck. 25 years proves it.

These subs hit hard I had them in my Toyota Avalon. One thing I would recommend is running them at the recommended amp power...I was running a 1000 rms mtx amp and blew them out..using with the recommended amp power should be fine. Great beginners subs..

Purely Awesome

August 13, 2013

I was looking for a sub to replace the blown Cerwin Vega in a home theater powered sub I came into. This had the right size, screw holes, wattage and resistance to replace it. It has been fantastic and adds a new level of acoustics to my system. MTX is fantastic, at any price, even the less-expensive end.

Mtx is great

September 25, 2012

This isnt the loudest sub mtx makes. But for this price range of a 12" sub, this is one of the best. Mtx audio takes pride in their audio and builds it for durability as well as quality. So you can plan on any mtx product to last as long as you want it to. And Sonic has the best prices around.

whatever sub

May 22, 2012

I bought this at a bundle with a 350w Kenwood amp from sonicelectronix. when i first put them in it hit pretty hard and put out some good clean bass but after only a month of bumpin around it started to have this ugly crackling sound at higher frequencies... wont be getting another one of these. maybe i just pushed it too hard being that it is only a 400 watt sub, even though it was only getting 150w RMS. Ehh.

good beginner subs

February 7, 2012

I've owned these subs for about 9 months now. They have lasted great through the abuse. Ive had this sub on 3 amps (dont buy kenwood amps), and in two different boxes, one in old lexus, and the new ported one in my ranger. From the beginning i was overpowering these subs by 50 rms a piece. Now, they are being run by a hifonics 1000.d amp at 2 ohms. so in short do these sound good on 750rms, No they really dont, i have to turn my radio to -2 with the gain all the way down on the amp. But i have to say Ive played these subs for at least an hour a day for the past 9 months driving back and forth to school at a excessive level and they still sound very good although they dont want to handle some frequencies now probably my fault though.

Conclussion: great beginner sub but if you want to go to the next level you cant go wrong with re-audio's se series at least that's what ill be upgrading to.

Can this amp run two MTX 12" Terminators @4ohms 200watts RMS or do I need more power?
A shopper on Dec 15, 2014
MTX TN12-04
MTX TN12-04
Rockford Fosgate R750-1D
Rockford Fosgate R750-1D
Best Answer: Hello,

Two MTX Audio TN12-04 CANNOT be wired to a 4ohm final load, that is impossible. Two MTX Audio TN12-04, when wired in parallel, will be asking for ~400w RMS @2ohms. This makes the Rockford Fosgate R750-1D a solid choice. However, you save a bit on your budget by going with the Rockford Fosgate R500X1D instead, as it provides 500w RMS @2ohms, making as good of a match!
