Hertz CS 300 S4 + Free 12" Sealed Encloure

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.

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!

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.
