Incredible Bass with Ability to Perform in a Tight Space!

NVX's VC-Series car subwoofers are about to blow you away. The VCW124 is a jack-of-all-trades and has been engineered to the highest standards. The woven fiber pressed paper cone and custom High Roll foam surround with Nylon stitching help reproduce tight and accurate bass, keeping cone distortion to a minimum even at the highest volume levels. The next key components in the design of the VCW124 are the large dual 3" High Temperature Aluminum voice coils and triple stacked motor structure. With all of these features combined this sub can handle some serious power at 850-1000 watts RMS. The dual voice coils also give you many options for different Ohm load wiring configurations.

With all the above engineering elements combined, the VCW124 subwoofer gives you a better sound and build quality of many subs costing almost twice as much. They even sound amazing in small sealed enclosure for people with limited space!

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.
VC-Series (NVX)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
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.
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
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".
87 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.
Dark Gray
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.
Woven Fiber Pressed Paper Cone
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.
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.
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.

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
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.
2.5 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.
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.
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.


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
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.
3.20 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.

Amazing Subwoofer

October 13, 2014

Has a very good feel and structure very solid. Large cone area much better than average stitching and craftsmanship. Mine sounded amazing squeezed the trunk of a VW Golf but you will be heard, Make sure you give it accurate power because of that new motor rating wattage requirements I had mine going for 7 months at around 1200 watts and finally the voice coil was shot.

Amazing Deal! So Far So Good

October 24, 2013

I bought this sub to install in a friend's car. I bought it with the free ported sub box deal for a fantastic price (Although it didnt fit in the box so I had to sand it down by about 1/2") Regardless this thing suggests about 900 Watts RMS in a ported box (I ran it off of a Rockford Fosgate 750-1D). Sound clarity is amazing and it gets some seriously crushing lows. Its almost as loud as my 2 15" Kicker CVR's in just one woofer! Overall great sub, i would definitely recommend it!

Best sub I've had

February 8, 2015

I have this sub running at 1 ohm on a BRX1100.1D mono block

Sub says it's rated at 850-1000 watts rms
But nvx undertakes their speakers so in sure it can handle more cuz mine BANGS and no clipping or distortion
ALSO I have it on a ported box which this sub recommends using a ported/vented box

Best subwoofer I have ever owned.

April 30, 2015

I install car audio and have for the last 13 years, this sub surprised me in the best of ways. It looks amazing and sounds even better, I have turned everyone that hears it into a NVX consumer. I have one in a custom 2.4 cu ft ported box tuned to 40 hz and my SUV flexes everywhere lol. SQ and SPL is unmatched oh and it is taking over 1000 watts like a champ! Give it good clean power and you will be living in your car lol. Buy NVX and support the next big thing to happen to the mobile electronics world before they realize I would have paid 400 for this sub haha. Amazing amazing amazing.

NVX VCW152 - 5 star

August 23, 2013

Because of budget issues it will take a very long time to finish my orders & I intend to order every item before beginning the install so I don't have to redo anything, hopefully. The NVX VCW152 is everything as described at sonic and at a extremely good value, especially with a free tuned box. It does have a heavy triple stacked magnet with a rubber magnet wrap as in most high grade subwoofers. To leave this review I have to guess on durability. I give it a 4 star only because there is no re cone kit but for the price I'm not complaining. I'd avoid cheaper subs that hide the magnet.

Heard many great things about this speaker, exceeded my expectations
Danny G on Jan 27, 2015
How is the durability and sound quality of this sub? I am having it shipped outside US
Matthew M on Jul 18, 2015
Best Answer: I had this in my last setup, and all I can say is it's INSANE! Very durable, even beyond their power rating!
I was pushing mine with about 2500w rms and never had an issue. I was careful with it though, obviously.
It sounds far better than any other 15" I've ever owned...and I've had many (Treo, Soundstream, many others).
You wont be disappointed ;)
