Very good box

I have this box with a soundqubed hdc3.0 12 and thing gets down and the sub isn't even at full power yet it is a must have for a 12

Massive box

Since owning this box I have run a 1000 watt RMS subwoofer inside it and currently replaced that with a 1500 watt RMS subwoofer and have to say it’s made for incredibly low range from both subwoofers. My only issue was the port was loose inside the box and had to re-glue it but it’s still holding together with all this power. Very pleased.

Sick Box

This box is a beast. The finish on the box is a beautiful black metallic. The box itself is huge and has a massive port/vent on the side. I believe the vent is 13 inches tall by 3 inches wide, I have a Massive Audio Hippo XL122 in this box and it slams. It is being powered by a Hifonics Colossus 3200 LTD and the combination is perfect. Coming from a custom made box this box is noticeably louder and I would recommend this enclosure for anybody with a single set up looking to slam and get the most spl out of their system.

Pretty good

It is a decent box and the coating on it is a nice alternative to carpet. I'm not blown away by it at all. The big "bass" carved in the top is kind of cheesy but it won't be seen in my truck. Only the front baffle is 1" the rest is smaller. Mine arrived in a cardboard box with no protection and subsequently had a dent on the edge which split a small section and cracked the coating. I chose not to attempt exchanging for fear of receiving a more damaged replacement. A little glue and some clamps overnight seems to have made it look better.
