Thunderous Bass Impact

The chill finally crawls from off of your spine. For a moment there are no words that can describe the gut-wrenching bass tones you just heard. The next moment, you can’t stop thinking of new ways to let the world know of your experience. You’ve just been exposed to an MTX Audio T9500 superwoofer, and you won’t soon forget the experience. These subwoofers are an industry standard for those looking to make bass tones once thought unheard stand out right in your face and make their presence known.

Boasting a rating of 1000 watts of true RMS power handling, these subwoofers can really handle some power! A 260oz. magnet allows the T9500 subwoofers for a full 4” of peak-to-peak excursion! This means with the Thunder 9500 you get a full 1” of Xmax. A 4” voice coil allows for some mean bass reproduction and can really help reproduce the gut-wrenching deep low bass that a lot of SPL competitors are after.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Thunder 9500
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.
2000 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.
1000 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
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
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).
31 - 150 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".
88 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.
25.4 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.
Silver
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 Carbon Filled Polypropylene w/ Aluminum Deposition
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.
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.
1.0 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.
1.5 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.
1.75 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.
1.75 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.
9-3/4"
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"
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.

One of the loudest I've heard

August 12, 2008

This sub is great. I recommend it to anybody that can afford its high price. The 1000 watt rating is bs. I've seen it handle 1500 watts like it was nothing. It is loud and the sound quality is great. I've never heard a w7, so i cant put in an opinion about which one is better. Overall, its a kick ass sub.

mtx amps/subs vs jl audio

October 20, 2006

Ok. First off, I personally dont have this sub, I would never waste money on MTX but unfortunately my friend did. He bought one of these and one of the mtx TA81001 amps "1000 watts". Its sound quality was horrible compared to my 12w6v2 with a 500/1 and his was barely louder than mine. Both were in dealer made custom ported boxes. Not to hit on this sub because overall it is a pretty decent value but, as for the guy saying that he put 4x 1000 watt mtx amps on his 9500, try putting 4 jl 1000/1 amps on it and see what happens :). Overall this is a decent sub but u would enjoy a 12w6 much more.

PHAT Subs!!

November 28, 2005

I own 2 of these bad boys. I have them crammed in a 1994 Mazda MX-3. They are hooked up to a 4000watt HIFONICS BRUTUS amp, and they slam the piss out of the car, causin my back hatch flex like crazy. The sad part is the amp is turned down because i dont have enough battery power to pound the crap out of them. If you have the money buy them. I got lucky and bought them brand new for $250/pr, and they're are worth so much more. If you hardcore into to subs and SPL, then these subs are for you!! But becareful these thangs are HEAVY!!

I have two 9500's each in a 2.25 cubic pro box.each have a MTX TA81001 pushing them in 2 ohm configuration and these things pound so hard. They are rated at 1000watts but birth certificate says 1550watts. Don't know how many dbs it hitting but well over 130 i'd say. They have a pretty price. But if u want a sub that can handle everything you can throw at it this is for you.Just take the challenge and you will find out for your self

Very nice sub

November 9, 2007

I have one of these right now and just recently ordered a second one...They pound very good for a single 12 inch sub. I would recommend getting one if it is in your price range. I am powering mine with a mtx 81001 amp and can't wait to get my second one.(just one of these is louder than any 2 12's I have ever seen(at my school)) I did have one problem with it, I was playing some extremely low tones and the tensil lead ripped off of the former. But I sent it back to mtx and they replaced it.

Mind over Matter

October 12, 2007

I have one of these subs along with a te1501d and in a sealed enclosure. This sub is well capable of doing some good handling, and if in a sealed rather than vented enclosure will hit the notes most claim they can't. If your looking for a sub that strokes at subsonic then this isn't for you, resonance hits at 31hz, and also is changed by the enclosure that restricts certain frequency along with the shape of the car that also eliminates certain resonances. Basically when it comes to math, the JL w7 is a louder sub by 1 dB which = 1/3 more power as 3 dB = 3* more power. Most will say "but mtx has a higher power handling rms" that doesn't really matter when it comes to dB sensitivity which in the end JL takes the cake..Im a hard earned mtx fan but I do my homework, JL is the better sub if all elements are properly setup, to the naive stereo installer a walmart bought pioneer installed by a pro is potential to out due a competition subwoofer installed by an amature.

JL Audio W7 vs. MTX 9500

January 30, 2006

I know how everyone thinks that this efficiency thing really matters. But when you spend this much on a sub. Who cares about what it'll do on a little cheap amp. I have 2 of these MTX 12's and the "rated power of 1000 watts" is bull. I have 4 1000 watt MTX amps on each coil on each woofer and have had that for 6 months so why don't we try hooking up 1500 to the JL and see what it can do besides pop. This sub is way heavier than a JL for a certain reason. So if all of you JL fans think your sub can outperform this sub power for power step up to the plate. The JL costs more maybe louder on a "little" amp but lets talk about real power and what the subs can really take. The XMAX's aren't even close. I've been up against the JL's in DB drag race and the guy had 1000 watts on each JL and there was a 3 db difference with the MTX's being louder. I'd compare the W7 more to the Rockford Fosgate T2.

Heard em both, and a little math

December 20, 2005

Aight, first off, i've heard the 12W7 and this sub. There is by far no comparison between the sound quality of the JL and the MTX. JL knocks this one out of the park, but W7s are still over rated, however, this sub is a better value than the W7. As for the guy who says 1000 watts is better than 750, let's do some math. The JL has a sensitivity of 86.5 (depends on the source), and the MTX 84.5. The formula for SPL is as follows: SPL = sensitivity+10log(watts).

So if we take the JL, plug it in at 750 watts, we get 115.25 dB. The MTX at 1000 watts cranks out about 114.5, thus the JL has a louder sound pressure level than this sub, so please, before you think you are all awesome and you think more watts=more power, do some homework. Point being, however, this is a decent woofer, especially for the price, so don't discredit it entirely, still however, JL W7 will, i promise you, hit harder.

W7 Killers

November 14, 2005

These Subs blow W7 out of water. MTX is said to be the best, I am not going to agree, but they are up there with the rest. The power of the 9500 MTX 1000 watts RMS compared to the W7's 750 watts RMS. They can take a lot more power. In the car audio shops they make the subs sound a lot better than if they were in your car. So don't rate a sub by the way that they sound in the car audio shop. These are a dream come true.

I heard this sub in the shop today... dispite what MTX and others claim... this thing does NOT compair to a W7... besides it's lower price, otherwise w7 will blow it away no problem. If you have the extra money go w7, or for a compairable price go w6v2.

Bottom line, its a good sub, but DOESN'T compair to a w7.

I didn't buy this woofer from Sonic, I got it as a gift after my friend dropped it and ripped the cone wich took me 5 minutes to repair anyways. This woofer is awesome my friend has a solo x 12" with a 2000w brutus amp and my truck sounds about the same with a 1000watt hifonics HFI. Ohhh and the difference from my built to specs box compared to his built to spec box its amazing how small the box the mtx requires and his takes up his whole trunk of his suv. I LOVE this woofer. I'm guessing it would take about 1400 rms with no problem.

What gauge power and ground wire should i be using for 1 sub ?
A shopper on Oct 11, 2014
Best Answer: Hello,

That is determined by the Amplifier, not the Sub. However, if we are to assume 1000w from the amp, like the sub is asking for, then that warrants the need for No Less than 4 Gauge Power/Ground, preferably OFC.
