Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Dual 12-inch Sealed Car Sub Box Made with 3/4" MDF and lined w/Polyfil (2.46 cu ft Airspace - 12SQB)
Quantity: 1

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.

Belva MDF 3/4-inch Thickness

General Features:

  • Dual Sealed 12" Enclosure
  • Internal box volume: 2.5 cubic ft. total air space - 1.25 cubic ft. per chamber.
  • High Quality 3/4" MDF Construction
  • Durable black carpeting
  • Pre-lined with Poly-Fil
  • Seams are fully caulked for better efficiency
  • 2 Separate chambers allowing each subwoofer its own air space
  • Gold post terminals for clean and easy wiring access
  • Box Dimensions: 28" Wide, 14" Depth, 14" Height
  • 30 Day return policy

Heavy Duty!

The following review is for MDFD12, which is a part of the bundle you are viewing.

I would recommend this product for the guy's out there that are serious about their music. If you got good, high quality subs, then this box will make them perform to your sub's max output with out worry of blowing up your box.

The Box that Rocks

The following review is for MDFD12, which is a part of the bundle you are viewing.

Appears to be fairly well built. Arrived with a little dent and a tear but its too little to bother with. Sounds nice but doesn't hit as deep as I would have liked. Small size however, leaves me some room for a couple of bags of groceries. Three stars for durability since I've only owned this for about a month.

Amazing Enclosure, Even Better Price.

The following review is for MDFD12, which is a part of the bundle you are viewing.

Ordered this as my first enclosure, put two 12" subs in it and I haven't found a box that hits as hard and as clean as this one has. Will definitely buy from SonicElectronix again for my car audio needs.

Fast and easy great buy

The following review is for MDFD12, which is a part of the bundle you are viewing.

I got my complete set up: 12" kicker subs box 1000watt Mbquart amp and amp kit. I have always installed my own equipment, I found it helpful that they have videos that covered some of the product they carry. There are a few shop's in Texas like Best buy and Custom Sounds that offer equipment. But the professionalism of the knowledgeable staff the price and the reliability made it clear that I wanted to do business with them.
