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. These features combined help this sub 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 better sound and build quality than many subs costing almost twice as much. Plus, they will sound great in a small sealed enclosure for those who do not have a lot of space!

NVX VC Series Subwoofer Breakdown

Surround: Most materials used in commercial subwoofer surrounds rip and tear at peak levels. Keeping this in mind, the NVX team developed a custom high-roll foam surround that gives their subs improved linearity and MORE output. Combining that with high-strength adhesive and nylon stitching means that this subwoofer will last through some serious audio output!

Basket: The 3-dimensional cast provides outstanding strength while keeping the subwoofer light due to the aluminum construction. Aluminum is a non-ferrous metal, which means the basket will not interfere with the magnetic energy of the voice coil and motor structure.

Spiders: The Dual Poly-Cotton Spiders are designed to be durable and long-lasting. They give the voice coil the suspension it needs and restore the subwoofer to its normal resting position with ease.

Voice Coil: The 3" (2.5" for the VCW102 and VCW 104) High Temperature Aluminum Voice Coil along with the triple-stacked magnet give massive power handling capability for the VC Series Subwoofers. The effective heat dissipation of the voice coil allows you to play the subwoofer louder without distortion.

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.

Belva Subwoofer Boxes with Polyfill and 3/4-inch MDF

Built for Bass

You've got an awesome subwoofer there, pal. But where's it gonna go? You can't just throw that thing in the trunk and call it a day. Don't worry, Belva's got your back. With superior construction, great features and everything you need for bass, you'll be ready to pass up that entry-level box you've been eyeballing.

Belva Subwoofer Boxes are CARB Phase 2 Compliant

You get quality boxes with solid 3/4" MDF because nothing else will do the job right. You want to flex your windshield, not your box's innards. You get polyfill built into the box, making sure your subs perform perfectly. On top of that, you get a box that's CARB Phase 2 Compliant, meaning your box won't emit as much nasty formaldehyde as the competition. Better for your bass and better for you.

Belva MDF 3/4-inch Thickness

Look, nobody buys a subwoofer and says, 'Aw man, I just want a teeny bit of thump.' Naw man, you want something that kicks you in the chest, but you need a box that's gonna put up with it. That's where Belva comes in. While other brands use less-than-optimal 1/2-inch MDF, we've got 3/4-inch MDF to make sure you get all the bass you can handle. Why risk a busted box? Belva's the obvious choice when it comes to giving your sub a good home and giving you the low end you're looking for.

Extremely Accurate

The following review is for VCW124v3, which is a part of the bundle you are viewing.

For a $200 subwoofer driver, this piece is one of the most accurate in it's price bracket.

What does it do for you? It creates a listening pleasure like no other, whether you listen to classical, rock, pipe organ, or any other genre of music, this speaker delivers.

It's quick response is well appreciated. I would or could go on and on about the different setups and what yielded the most listening pleasure, but that would be highly selective to my ears.

Bottom line is I would recommend this speaker on any given day of the week.

Best subs yet!

The following review is for VCW124v3, which is a part of the bundle you are viewing.

I bought the NVX VCW124s (2) to use in my vehicle with a Hifonics Brutus 2200 RMS Monoblock amp. The subs Voice coils are hooked in parallel giving me roughly a 2 Ohm load per speaker. So these babies are capable of getting 1100 amps RMS each but I don't push them that hard because I really don't need too and I want them to last. They hit harder than any sub I have ever bought and I am a solid NVX believer now. I also just bought the entry level NSW122s at a great deal, 2 for $99! If you are thinking about these, DO IT! You will not be disappointed one bit, and then you will likely not even consider anything else but NVX when it comes to serious performance and value.

The following review is for VCW124v3, which is a part of the bundle you are viewing.

That's all these do is POUND! They sound amazing. I have them ran 1 ohm to my Hifonics X2200.1, giving them 1000 watts RMS easily, and they are begging for more. Can't wait to get them in a custom box (going to do 1.9 cubic ft per chamber tuned to 30-34 hz), and have them really perform. NVX is great quality, and sound amazing. Heads turn when you have these in your trunk!!!!
