NVX X-Series Subwoofer Breakdown




Hybrid Cone

Egyptian Papyrus-Blend Cone

The NVX X-Series features an ultra stiff, lightweight cone material custom made from finely milled pulp & Egyptian Papyrus fibers. The cone is treated with a soft matte black finish for a stylish and modern look.

Vertically Attached oSD Surround

Patented Surround Technology

XQW woofers are engineered with a unique oSD (oversized SD) surround. This patented technology involves attaching the surround on a vertical edge for increased surface area, which translates to more bass. Additionally, the surround itself is constructed with a multi-radius elliptical edge for incredibly symmetrical, linear cone movement.

Aluminum Shorting Ring

Aluminum Shorting Ring

Another feature which seperates the X-Series from other woofers on the market is the innovative aluminum shorting ring. The shorting ring is basically a conductive aluminum ring placed between the pole piece and the voice coil former. This ring will essentially reduce the negative effects of the inductance which is inherently present in any loudspeaker. In short, this shorting ring:

  • Improves power delivery to the voice coil
  • Decreases distortion
  • Contributes to linear cone movement
  • Improves high-end extension
  • Decreases risk of overheating

Optimized for Small Enclosures

Space Efficient Design

These subwoofers only require 6" of mounting depth to produce intensely powerful bass. NVX utilized the latest loudspeaker technology to design a space-saving subwoofer without the anemic sound of typical shallow-mount woofers. NVX claims that the X-Series is "The discerning listener's alternative" to such shallow subwoofers, and we agree.

High Temperature Voice Coil

3" High-Temp Voice Coil

The stout 3" high temperature voice coil is constructed from a copper wire wrapped around an TSV TIL former. This industry standard design is powerful enough to readily drive the cone with strict linear control, yet at the same time remains efficient enough for the compact, space saving magnet structure. The black appearance of the coil is a result of the special treatment which is applied to improve power handling and heat dissipation.

Low Turbulence Basket

Custom Cast Aluminum Basket

The custom basket of the X-Series woofer is striking in terms of both aesthetics and engineering. A particularly open basket was designed in order to improve airflow for superior cone response and reduced back-wave interference. NVX engineers chose aluminum both for its exceptional strength-to-weight ratio, as well as to eliminate interference with the magnet structure.

High-Excursion Tinsel Leads

High Excursion Tinsel Leads

The tinsel leads used in the X-Series woofer are a small example of the incredible attention to detail of the NVX engineers. These tinsel leads are attached at the basin of each fold in the spider with sufficient slack for full excursion. This prevents damage to the leads from the movement of the cone, while also keeping them securely attached to prevent mechanical noise.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
X (NVX)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
3"
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 - 200 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".
89 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.
20 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.
Paper
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.
Foam
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
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.
0.80 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.
0.92 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.
1.1 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.
1.43 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.
5-3/4"
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.
12-1/16"
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.
29 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.
64 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.
0.38
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.
0.41
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.
5.8 ohms

Incredible Sound Quality and Punch

December 26, 2013

The following review is for XQW124, which is a part of the bundle you are viewing.

Got a pair in a 1.5CF per side, FoxAcoustics box, tuned to 35htz, and wired to 1 Ohm, delivering 1100 RMS on a massive D2400. The sound quality is second to none. Transitions are tight and very pleasant. I can feel the percussion and get plenty of SPL. Beat the REAudio S E X hands down. Amazed at the quality of the woofer, and what it delivers in such a small enclosure.

SQ Sub

September 18, 2014

Bought this sub buy one get one free. These subs sound great and get pretty loud as well. the subs came already wired to 2 ohms, but the wire seemed much too thin for 600 watt subs. I'm guessing around 18 awg. I replaced it with 12 gauge wire. I have them hooked to a pioneer 1200 watt rms amp and they seem to take the power quite well.

Great subs if you can get them for the right price.

April 8, 2018

The following review is for XQW124, which is a part of the bundle you are viewing.

I had originally bought the ported box for this XQW124 for one of my DC Level One 12 inchers. Had to do a minor mod to get the DC to mount and it sounded great! No doubt! DC is fan_asteriks_tastic! I then decided to buy another DC Level One 12 incher to run them in pair so I didn't need this box anymore... Or so I thought..... And then I decided to give this X-Series sub a try since I had the box for it already... And oh yeah!.. This sub sounds great! Hits notes with SQ and SPL. It is loud, clean and articulate! Now I want another X- 12" and another specific ported box to run these in pair!!! Great subwoofer, great bass, great box and definitely worth more $$$!! I want X-Series decals for my vehicle now! LOL. Great product by NVX!!!!!..... And great everything else from Sonic!!!!!!!!

10 years and my search is over.

December 8, 2017

The following review is for XQW124, which is a part of the bundle you are viewing.

I've gone through just about every sub there is from typical lower end Pioneer, kicker, alpine, etc to image dynamics, JL, focal, eclipse, infinity kappa perfects. even offstream brands SD, DD, SQ, Skar, Arc, etc and EVERYTHING in between all brands all sizes. For the price point of this woofer the build and the absolute sound quality w crisp clean deep and accurate punchy bass. This sub is one of the best ive owned and heard. Its ran off the 5th channel from my JL slash 500/5 with a 1.5 cu ft net tuned @ 34hz. This sub wants more power so I will be getting the JL HD900/5 soon. But the accuracy of this 12" is outstanding. I do recommend at least 350 watts ported and at least 550 watts sealed. If your a bass guy you will need two of these with a quality 700-1000 watts. 1 is good for your average person and will fill any vehicle with bass.

Amazing subwoofer

August 27, 2017

The following review is for XQW124, which is a part of the bundle you are viewing.

I'd recommend this subwoofer to anyone looking for a quality subwoofer, with a great mixture of sq/spl!! Sounds amazing and the build quality of this subwoofer is very impressive for the price!! I had an enclosure made for this subwoofer at 1.9ft^3 tuned to 29 hz and the sound quality is phenomenal while hitting super low notes as well. Big upgrade from my JL audio w3v2 12". Not that much louder in this box during break in but it sounds much better. Would buy this again and recommend to anyone looking for a great all around sub. I've owned Rockford p3, pioneer champion pro series, kicker cvr, etc and none match the quality and sound quality of the subwoofer .

High quality subwoofers. Don't let the price fool you!

August 14, 2017

The following review is for XQW124, which is a part of the bundle you are viewing.

Bought two of these along with the NVX ported enclosures built for them. I also have 40 sq. ft. of NVX sound deadener throughout my car. These things put out nothing but pure, clean bass. No unnecessary rattles and no extra vibrations other than the notes being played. I've previously had 2 dual kicker l5 12's setups in sealed and in ported enclosures. These aren't quite as loud as the L5's in the ported enclosure but that's more to do with the kickers taking 1300rms and these getting 800rms. These sound so much better than the kickers. and were much more affordable. It's unbelievable how much woofer you are getting for $200 a pair. The Kicker L5's costs 400-450$ back then and even more now (L7's). My only complaint is that I wish these were rated at 600+watts rms. I'm sure they can handle it just fine but I don't want to chance going against manufacturer specs and voiding warranties. Highly recommend this as well as NVX enclosures and sound deadening.
