Great value

Not much to say, a quality box for the price, would recommend it for sure.

AWESOME BOX

I have a DUB MAG 1200 Sitting in this box and all I can say is that this box hits HARD!!. Now first off for those of you who don't know, you are actually going to get the best base response with a sealed box and I would definitely recommend this one. It is also not too big and is good for about 1.5 cubic feet of volume. Also I have a 3000GT which is notorious for it's shallow trunk and small amount of trunk space and this box fit easily with room to spare!!! So this is definitely the box for you if you are looking to save space and/or want to have excellent sound.

Solid

It's a very well constructed box. It does the job and it does it well. One thing I noticed when I got it was how strong the box felt. Good product!

Excellent Quality

I would recommend this product to any of my friends for the simple fact that it was inexpensive. They usually say, you get what you paid for, but in this case you get more than what's expected. I've been running 1 Alpine Type R 12" in this enclosure and could not be happier. The box is on the smaller size but is perfect for allowing my subwoofer to maintain that tight and accurate bass. I am for sure going through Sonic Electronics for future subwoofer enclosures!

Perfect

A great small size and puts out a loud boom, great for the money.

Sub Box, 6 months later

Overall I've been very happy with this box. It seems pretty responsive and seems to be sealed properly. Though I'd still highly recommend it, I have had two minor issues with it:
1. The first day I had it hooked up my bass kept cutting out. Took a look and the back side of the terminal (on the inside of the box) were loose, creating a poor connection. Simply tightened it up with a screwdriver and haven't had issues since.
2. I just noticed that the carpeting is starting to pull away in 2 spots. Granted, it's pulling away where I usually grab the box to move it, which I do fairly often.

Overall though, I'd recommend the box if you're needing a sealed, compact box for a 12" sub.

1cubic foot sealed enclosure

I have picked up this enclosure from here. I must say the fabric matched my car fabric to a T and this box also no kidding around made my sub sound twice as better then it did in my old fiberglass box it was first in.

Box

Box seemed kinda small. My Alpine Type R is Recommended for 0.7-1.0 and I got this one. I just seems like its more for a 10. It puts out, I don't have a complaint about it. Great box though

Great Sound

Filled box with fiber and mounted Infinity Kappa 12". Compliments the music perfectly with 500W mono amp. Plenty of boom if you want it.
I sealed inside seams whether it needed it or not. Would have been tough to fabricate myself for the price. Good value
