Box for two DD3512's

[imhungnurnot 9]

I built this for a friend of mine. Its about 2.52 cuft per sub with 40 square inches of port per sub tuned to 36 Hz.

The objective was to build a box that filled up the back of his truck. But that was too much air space overall, so we pretty much built a box inside of a box..

The pic of the inside looks pretty sick.

Box looks good!

May want to take it easy on the screws and use more Titebond wood glue!

How does it sound?

Good. It is a pretty musical setup. The subs are getting about 1500 wRMS a piece from two SAZ1500d's strapped. It did a 143.9 db on the kick, front windows down. It was only a sweep (100hz-30hz). He might get another db or so with a burp. I could have tuned the box lower, but I didn't want to shy too far away from DD's 39-40 hz tuning recommendation. Also, the subs are firing into the driver and passenger seats. This may make it meter lower. We made drawers under the box so the two sundowns can slide in and out. It's pretty cool. I'll take more pictures.
