Amazing Value!!!

This enclosure was totally worth every cent! Visually impressive-though it takes up a little more space than my old one, completely worth it. Pours out incredible clean bass that I can feel in my soul w/ dual 10" Kicker Comp-Rs'. Make the upgrade like I did! You won't regret it!

great subwoofer

This sub box makes my subwoofer s sound better than they should of had.

Does what it should

This sub-woofer box really does what it should. With a pair of good drivers you can get great deep bass sound out of it. The finish is pretty good as well with a lacquer finished face plate.

Perfect fit and lots of style

This enclosure is was chosen to house a pair of Rockford Fosgate R-2 10's and was a perfect fit. The sound quality was top notch with its separately tuned chambers that were pre- poly filled. The glossy beauty baffle with the chrome studs holding it on is a perfect touch of classy style that is as pleasing to the eyes as it is on the ears. Super fast shipping and fact that it was purchased from Sonic Electronix make it super easy for me to recommend this product to anyone looking for a great sounding and great looking pre-fab enclosure.

Belva Sub Box

Good quality and durable product. Was very easy to set up and fits perfect in my car.

perfect box for the price

I bought this box especially for the NVX V-series 10" that i order earlier from Sonic Electronic. My old box was a small seal box and it didn't sound like i wanted too.. So i decide i should try out a ported box.... After looking around Ebay, my local pawn shop and crutchfield, i could not fine what i was looking for and the one i wanted was over price. Thanks to Sonic Electronic i found the right box and price for my sub..The bass are louder then my seal box i had before. Thank You.

Ported Box

This box is just what i needed , made my subs come alive . Had another ported box but not enough air space . This box really made my subs hit so much better.

All that and more.

This box is a perfect fit not to big not to small. Toned to i think 30hz. The look is clean and well made. The price unbeatable. For anyone looking to add 10s this is a no brainer. Get one before everyone else does. 5*s all day.

Great product!!

Nice design great quality and excellent performance will buy again highly recommend it. and affordable price

Good subwoofer box for the money.

I had a pair of 10-inch Polk MOMOs that I wanted to use and so I bought this product. The box was very well made and felt solid. I'm am pretty thankful this box came with polyfill. 2 issues I had with this box was I had to solder wire to the terminals and the cut out hole didn't really match my subs. I tried for an hour to align the subs with the edge of the hole but I could only manage to do 4 screws per sub. The other 4, the screws would rub against the hole. Even with the screws gone, the box performs well and the notes hit hard.

Really Need to Change the Specs

The box is 30.5x14x14 which equals 5978. Divide that by 1728 to get cubic ft. and you get 3.46cu’ft, after you estimate port displacement you would subtract roughly .6 to get your total cubic ft of the enclosures which is roughly 2.86cu’ft. If you wanna get the cubic feet per enclosure you divide that by 2 and get 1.43cu’ft. Seems to me like they found the total cubic feet of one chamber and accidentally divided it by 2 thinking it was the total volume of both chambers. Looks like a good box though and I plan on getting one as long as I’m right lol. If not .71cu’ft is wayy too small for any 10 haha.

It’s AWESOME!

It works so well with dual 10 kicker comps shakes everything in the car. Highly recommend this box.
