NVX XQW122 (Newest Version)
800 Watt Peak (400W RMS) 12" X-Series Dual 2 ohm Car Subwoofer w/ Aluminum Shorting Ring (XQW 122)
NVX X-Series Subwoofer Breakdown
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.
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
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
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.
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.
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
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.

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".
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.
Recommended Enclosure Specifications
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.
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.

I bought this sub as my end-all-be-all sub. I have a 2011 dodge ram, so fitting 12" subs and up is a bit of a difficulty. I had this sub in a 36HZ ported box that was on the verge of too small (around 1.1 cu ft) but it was still super responsive and hit beautiful notes. It also too all 1200 watts at 1 ohm that the JAD 1200.1 gave to it with no problem.
I finally purchased a vented underseat box from Fox Acoustics, but this model was too big for a 13" max opening, so I decided to change to the VSW122. I brought this sub into my house to use as a home subwoofer and I'm glad I did. Even in it's small volume box, it runs circles around the factory purchased 12" that I had. I purchased a 4" aero port and will be building a new home sub box to spec for this XQW. This sub is the BEST sub I have ever owned and it definitely competes with subs in the $300+ range.

I was scared to buy a brand I never heard of but I said to myself No Guts No Glory so I tried them and they made me a believer in Nvx is was clean bass and deep bass I am still in shock like wow they sound better then the alpine type and the kicker comp x I am pushing the two Nvx dual 2 ohms with a kicker zx 750.1 at 2 ohms if u hear it you would threw you system that you have now and replace it with Nvx
