MTX Audio 55 Series Subwoofer

MTX 5515-44 55 Series Subwoofer

The MTX Audio 55 Series subwoofers are the perfect solution for improving your car sound quality while taking up little space. Their low profile means they do not need a large enclosure and will still deliver powerful bass. How do they do this? With an improved surround compared to traditional Half-Roll surrounds, expanded surface area and reduced distortion due to progressive suspension controls. With over 40 years of audio experience, MTX Audio makes sure and knows how to create quality audio with their products, and the 55 Series is no exception!

MTX Inverted Apex Surround

MTX Inverted Apex Surround

The MTX Inverted Apex Surround increases the surface area of the sub to allow for more air movement, accurate bass reproduction and higher SPL. Traditional Half-Roll Surrounds have an inherent wrinkling when reproducing bass due to the physics of its motion, which causes distortion. The Inverted Apex Surround moves symmetrically through both positive and negative cycles which eliminates this type of distortion.



Progressive Suspension Control

MTX Audio Series Subwoofer

Progressive Suspension control the excursion of the subwoofer at high power levels which reduces distortion. Eliminating this 3rd order distortion means you can play your music loud and rely on your subwoofer to take of itself.



Radial Ribbed T-Yoke

MTX Audio Series Subwoofer

Two features really make sure the MTX subwoofers stay cool: the Spider Plateau Venting and the Radial Ribbed T-Yoke. The Spider Plateau Venting is a mechanical cooling process that targets cool air at the voice coil. This means the subwoofer cools itself as it is playing. The Radial Ribbed T-Yoke acts as a heat sink that dissipates heat and decreases distortion.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
55 (MTX)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
15"
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.
800 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.
400 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.
2"
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).
20 - 130 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".
95 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.
15.24 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.
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.
Single 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.
1.5 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.
2.48 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.
24 Hz
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.
173 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.
0.79
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.
1.21
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.
1.67 ohms
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.

OK wire if you like red wire

February 8, 2014

The following review is for BBSW167, which is a part of the bundle you are viewing.

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

June 20, 2014

The following review is for 5515-44, which is a part of the bundle you are viewing.

Been an MTX user for many years and they do not disappoint with this sub. Matched with the MTX500.1 amp in a sealed 1.7cu box, this sub hits low and deep. Smooth bass is the best description I have. The inverted surround rim gives it a low profile look and the double red stitching matches my interior nicely. If you have room and want something different from everyone else's 2 12" set ups, then this is the sub for you!

This is excellent speaker wire. One wire has round insulation while the other has square insulation making it easy to identify hot and grounds. My only installation problem was I didn't order enough. I needed a quantity of 2 just to wire a single cab pickup.

October 15, 2016

The following review is for 15SQV, which is a part of the bundle you are viewing.

I would recommend this product because it complements my sub perfectly and it's build very sturdy. Make sure you check your trunk dimensions before the purchase of this product for it's a bit bulky and might take up quite a bit of trunk space but if you have your mind set on purchasing a 15" sub this must be something you are already willing to give up for great sound. I would also suggest you fill the inclosure with polyfill to add a deeper bass. Overall if you are buying any kind of enclosure for your sub I would highly recommend purchasing a ported one like this one A+ product
