Nice box

This is a really nice box. I have a Boston Acoustics G5 in it and it pounds!!! I wanted to save space in trunk by switching to small sealed box instead of the big ported I was using previously. I thought I would be taking a hit in SPL but surprisingly I didn't. Just a gain in SQ. And I gained about 50% more trunk space.

Good value

Great box for the value. I have a JL 12w6 in it and it sounds amazing. My one issue was the aesthetics, it arrived looking like it needed a bit more carpeting but for the price and sound quality i’ll take it.

Great Box!

I have an Alpine Type-X 12" Subwoofer that I had put in a ported box. It sounded great and it hit hard. Problem was that it was taking up to much of my trunk space and I wanted some back so I started searching for a sealed box.
I purchased this box after looking through several reviews of the boxes on Amazon. They appeared to be hit or miss. This box appeared solid and a different sized box from this manufacturer had good reviews so I gave it a try.
The box arrived well packaged and in perfect condition and appeared to be well constructed. The Atrend badge easily unscrews off if you would like to remove it. It had enough room on it that I was able to mount my Eclpise ZA1200 directly on to it. Great box for the price.
Now that I have my sub in the sealed box, I have some more trunk room although I sacrificed some bass (not as loud as it was) but I was expecting that to happen.
It is a great box!

I just received two of these boxes today. I put them in my 2017 Chevy Camaro. I have 2 Rockford fosgate P 2's and I have a Rockford fosgate T750X amp pushing them. Have them wired at 1 ohm. Man my system sound so good. If you dont have much trunk space this is the way to go. And the Rockford fosgate setup is amazing.

Solid!

I put my older P2D4-12 in this after gluing polyfill to the insides. Hits harder than I remember it hitting before. Attend makes SOLID boxes.
Thank you.

Quality craftsmanship, and a great price!!!

This Atrend 12SQL is a great box for any budget build. Even though it's listed as medium duty I've sampled various 12" subwoofers in this box with different amplifiers at various power levels and not once did it disappoint. This is a box you can install with little or no modifications and be pleasantly happy with the lows it produces.
