Sonic Sub Box: 1SL12-1.0 (Black)

The box is perfect for the simple enclosed box setup. The volume is small, so I just added some polyfill and now the box makes the sub's bass sound clean, with a good solid punch. So having polyfil will help with subs that need the cubic vol, if getting this box.

This was a really great box, it was well built and was airtight. Carpeting was very nice. I used this for an Alpine Type R 12" was all I could have asked for. I have now upgraded to a ported box, and of course it's a lot louder than this but hey, it's ported. I would totally reccomend this box to a friend.

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.

When I purchased a 12" Alpine Type R sub, I looked up the recommended size to mount it into. I decided to go sealed for sound quality (tighter and punchier bass) over ported for loudness, and went with this box from SonicElectronix because of its low price. The box looks great, feels solid, and best of all, my Type R POUNDS in this thing! I am very pleased with my purchase.

For the price I don't think you will find a better box. Better quality than I expected.
