great box

This box does the job for a low price! i have my 1000 watt sub in it and it hits hard. Great sealed enclosure for the money!

Enclosed Sub Box

This box was perfect for my 12" Hertz Sub. Built nice for the price, I did take the plastic wire conection out glue a piece of wood in its place carpet it and run and silacone my wire direct to the sub, no leaks or rattles this way. Also lined it with acustic foam and polyfiled it. Sounds great! Sonic also shipped it right out got it in like 3 days, Thanks Sonic for great products at low prices!

great price

Don't be fooled by the price. it is a very nicely built, low dollar box. I have a pioneer premier champion pro subwoofer in it and it holds up to whatever i put it through

Solid Box, Great Value

This box is surprisingly solid for the price, and the carpet seems pretty good. Would definitely buy again.

Solid Box

This box is a good box if your not powering too much. Im using a 300 watt sub for it and the box is holding up just fine. I have seen and owned way better quality boxes but this thing is still good.

Great Box For The Price

The box I received is completely solid. Great looking exterior and I performs very well under extremely hard bass conditions.

Good Box for the Price

The box was well made with gold connectors and carpet material outside. The box was strong enough to hold the powerful sub-woofer I put in it. The value for the price can't be beat.

Average quality at best.

The sub box was a perfect fit for my sub, with 3/4" mdf board. But was not of quality, the fabric. The fabric was not glues down properly or was it a strong material. It has started to peel in corners and from where the seams meet.
