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.
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.
750 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.
4 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 - 220 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".
83 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.
Triple 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.
0.65 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.
1.0 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.
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.
31 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.
24.96 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.
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.
6.4 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.

The sub that gives me the best of both worlds!

April 6, 2015

I was looking for a sub to offer me the tight sound of a kick drum on rock (U2-Beautiful Day) or country (Flordia Georgia Line- Cruise), with the ability to reproduce low end sound on bass heavy RAP tracks like Lecrae's "Take Me as I Am."

This sub is amazing, I have it installed in an Atrend JL W7 box tuned at around 30hz, I had to have the hole enlarged to fit the sub.

It is being powered by a Hifonics Brutus BRX1100.1D bridged down to 2 ohms with 800 watts RMS.

This sub fills the cab of my '05 F150 Supercrew with amazing and gorgeous bass reproduction. I have it placed sitting length wise in the back seat with the right rear seat in the up position, and I now can seat 2 in the rear and 2 in the front, so I lost 1 seat, but added the bass that is truly satisfying.

To sum it up, I have found the sub that just gave me the best of both worlds!

Don't hesitate to give this sub a shot, I can only imagine the SPL if you ran 2 or more in your vehicle.

Thanks Sonicelectronix, you really helped me achieve the sound I was looking for and I love going for rides just to listen to the stereo.

BIG sound front the small sub..

September 18, 2013

I had a JL 12W7 in a ported box and got tired of not having any trunk space. So I sold that off and got one 10" NVX dvc sub in the free sealed box (ported boxes were backordered)... I prefer to maximize the sound out of a sub with a ported box but, all I can say is WOW.. This little 10 in a sealed box thumps almost AS-GOOD as the 12w7 I had.. NVX uses a similar magnet frame setup as some other high end subs, which is typical of new brands. I am hooked, AND I have trunk space!! Kinda wish I had bought a second one.. Don't look any further, BUY ONE (or two) and you won't regret it.
The ONLY drawback was the sub did not come with mounting screws, and the opening on the free sealed box had to be enlarged because the sub would not fit.. minor biggie.

nice sound

February 10, 2013

I was looking to purchase the jlw3's.after talking to the service/support group at sonic they recommended the nvx brand. I was sceptical because I hadn't heard of nvx before.I decided to take their advice.I'm running two vcw104 in a .55 cut ft box per speaker in a GMC 1500hd crew cab powered by a jad1200.1. My expectations weren't really to high with the small enclosure and it bn down fire under my rear seat.
Just had everything installed several hours ago and they honestly far exceded my expectations.even with this being break in period subs sound great.cant waittill next saturday to go back And get amp set up tO really drive them.Great sounding speaker for the price,mounting depth is good.will fit in spaces other speakers in its class wont.seems to be made pretty good and sturdy.cons-dont really have any that i see far as durabitity time will tell,if they dont hold up ill update.great sound for a pretty good price.i would recommend
I'm running a pioneer 3400bvh deck with 4 focal door speakers Powered by the nvx jad800.4,two Vcw104 powered by the 1200.1 with nvx 1/0 gauge ampifier wiring kit.

Deep lows, outstanding SQL and a value that's unrivaled

January 18, 2013

The VC10 sub is designed to sound great and play loud with a price tag that beats its competition by a mile. I'm running this sub in a sealed .75cf box powered with a solid 800 watts continuous and I haven't been able to even get a hint of bottoming out. Even with its massive triple stacked BL motor the mounting depth is only 6" which will fit in just about every box. Thats not happening with a JL w6, a Hertz sx10 or a focal k2?sub. But the power handling of the VCW beats them all despite its compact size resulting in very deep lows. And it's dual spiders give it extremely good damping for fast response, outstanding sound quality and accurate reproduction. You can be assured that the specs are accurate in real world use. Before you buy do yourself a favor and compare the well known competition and you'll see that the VCW is a clear winner in price per performance. Doing your homework will only make you feel better when you hook this equipment up in your system. I couldn't be happier with my purchase and I'm willing to bet you'll feel the same way.

I have 1 of this 10" sub's in a ported box, & its loud...The bass is deep & clean. At first I was looking for a more popular brand (JL, Kicker, Pioneer...) but went for NVX brand & I love it. The design of this sub is great quality. It's heavy & beefy looking for a 10" sub.

Incredible sub, power, and best of all, low price!!

December 1, 2014

I absolutely love my NVX VCW 10-4s. They are the best subs I have had out of the 4 systems I have had. These are even comparable in power and how hard they hit to my old Rockford Fosgate T1 12s. For anyone who is looking for a high powered system in a small package that will amaze everyone, these are definitely the route to go. This was the first time the audio shop I use have used or even heard of NVX. They are now looking to add them to their product line that they sell. Everyone there was impressed by the power and size. I have them in a 2014 GMC Sierra 1500 in a ported dual 10" fox acoustic box. If I could do it over again I would do this exact same set up in a heartbeat. If you are thinking of pulling the trigger on getting these subs, definitely do it! I promise you will not be disappointed. They also have great durability. I hve only had them for 30 days but they have been torture tested (and so was I indirectly lol) when I played them for 5 hours straight, full power, heavy bass songs without a single issue. I did this twice during a long road trip.
