Power and Value with N-Series

NVX's entry-level subwoofer is anything but "entry-level." NVX has engineered the NSW122 with exceptional features, such as a polypropylene cone, Nomex single spider and a high excursion rubber surround. This all adds up to a sub that moves more air for awesome, responsive and deep bass. The 2" dual 4-ohm KSV voice coil gives you a wide array of Ohm load wiring options for different applications. With an RMS Power Range of 200-350 watts, the NSW122 requires less power to operate efficiently without losing bass quality.

Continuing with the excellent engineering is a stamped steel basket that provides exceptional rigidity and the spring-loaded, chrome plated push terminals ensure a strong and dependable speaker wire connection. NVX's mission was to create an exceptional subwoofer at an entry-level price without sacrificing the quality and sound that the consumer deserves. They have succeeded!

Additional Information:

*CEA-2031 Compliant: All CEA-2031 compliant loudspeakers adopt the same testing and measurement methods so comparing them side by side is easy. Loudspeakers include car speakers and subwoofers. The Consumer Electronics Association created new testing and measurement methods for mobile loudspeaker systems that define test procedures for rating the performance and physical size of speakers. This is important because you can now compare different speakers on the same playing field. Any manufacturers who adopt the CEA-2031 logo product mark can be compared evenly to other speaker manufacturers with the same mark.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
N-Series (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.
350 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.
2 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 - 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".
85 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.
8 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.
2.0 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.
27 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.
63.51 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.

Greatest value for subwoofers around

October 28, 2014

These subs are comparable to kicker comp vr's at 1/3 of the price and use less wattage. If anyone is looking for unmatched quality sound on a budget then these are the subs for you. I'm only pushing them with 250 watts each and they are slamming. If you're looking to shake houses then get four of these with a 4 channel amp that pushes about 250-300 watts per channel rms and you will be the king of the block. I've had kicker, Power acoustik, JLaudio and others and letter me tell you these entry level subs are great quality for the price.

I bought 2 NVX NSW 12s and built a 4 cubes slot ported box, and they SLAM! I have them on about 350 watts each and couldn't be happier. I did a lot of research prior to purchasing my subs, and for the combination of quality and price they're unbeatable. Love NVX and my entire build consist of their products and I highly recommend them to any and all.

Good Quality bang for your buck

August 24, 2014

I bought 4 of these in Jan this year (dual 2 ohm version), put 2 subs in 2 identical boxes, coffin style, with the subs both facing up, one behind the other, and the port facing the rear of the car, both boxes side by side in the trunk. All 4 subs together create a 1 ohm load. Both slotted ports are tuned to 32Hz. Im using the 2500 watt 1 ch 1 ohm RE audio amp (which is now discontinued), each box has approx. 2.15 cuft gross vol, with subs and port about 1.62 cuft. For 240 bucks for 4x 12s that rumble that much, it was definitely worth it. They have been pounding real clean and hard in the back of my 2010 bmw 5 series station wagon since 8 months now. As always, the service and delivery was excellent and fast with Sonic!!

Great Sounding Sub !!!

August 22, 2014

These sub's have great sounding deep bass. For the price you can not find a better sub. They compare favorably to the more pricer brands out there. I'm really impressed with the NVX brand. I'm planning on doing an all NVX sound system in my next ride. Sonic Electronix is The Best. Hands Down.

NVX for life!

June 2, 2014

after reading the reviews I decided to get a pair that was on sale for $99.98 to match with my MTX MXA 4001 amp. after receiving them I install them the next day at a 2ohm setting and man before I knew it the subs were pounding hard that's from just 400watts. sounded like my other system which is 2 Alpine Type-R pair with a Hifonics gladiator 1400.1D.

In plain words get the subs if you are on a budget and plus don't need that much watts to run these subs.

GREAT Subwoofer at an unbeatable price!

March 24, 2014

I bought 2 of these subs for use in a sealed enclosure hooked up to an 1100 watt Brutus amp, these subs POUND. Most people are shocked when they hear them, and even more astounded when I tell them how much these subs cost! I had a JL sub 12" sub that was soo clean and good sounding, but 1 of these subs at less than half that price got so much deeper and louder, it shakes my truck at low freqs! No debate if you want a GREAT, LOW PRICED subwoofer. Get this sub NOW!

I was really excited about these subs. After a long time of debating I got a couple. I got them and thought they looked really nice. I will warn you though, the glue that seals the surround on to the basket is very weak it took barely any pressure and the surround came off on a quarter of the sub. I didn't wanna deal with returns being it was only 50 bucks for the sub so I am just glueing it back together. I do have one installed and man does it pound. I hope I got a lemon because these things seem nice for the most part
