Good box

The following review is for 12SAL, which is a part of the bundle you are viewing.

For the price, seems like a good value. Box was bigger than my speakers called for, so that may be why I'm not super happy with them. (I bought 2). Construction seems solid and carpet finish is quAlity. Overall, I'd say 8.5 out of 10. JL12W3V3 installed.

Pretty good

The following review is for 12SAL, which is a part of the bundle you are viewing.

Like it, sounds great...no leaks. Had a Belva mdfs12 which I thought felt more solid but I needed a 1.25cu ft box for my sub. It does the job well so far

Solid build with perfect carpet job

The following review is for 12SAL, which is a part of the bundle you are viewing.

This enclosure is as solid as they come. They did a great job with stretching and tucking the carpet as well.

Nice

Seems to be well built. Put my RF P2s in them & they hit hard for a sealed box.

Great Value, Saves Time!

The following review is for 12SAL, which is a part of the bundle you are viewing.

Was going to make my own 12" sub box for a single 12" sub I was planning to install in my 2007 Saturn Ion. Came across this, and for the price you simply cannot beat this deal.
The thicker MDF makes the box very sturdy, and personally prefer the black fabric over traditional dark greys. Fabric seems tough, is attached with strong adhesive to the box itself. The inside of the box is sealed off great, I looked it all over and it was flawless.
There is a metal logo on the front of the box, I did have to relocate it further towards the corner to allow my sub to mount properly - not a big deal, and the metal logo is of GREAT quality, and is wrapped to protect its shine before installation. Adds a nice touch.
Definitely would recommend this. It's simple, effective, looks great and takes up minimal space in your trunk if that's what you are after like I was.

I love this box. It's compact and fits perfectly with the slope of the back seat. Would recommend for anyone needing a tight space box.
