Custom Ported Sub Enclosure Box for 3 12" Sundown Audio X-12 X Series Subs BIRCH

This listing is for a custom enclosure with 1/2" plexiglass window for 3 Sundown Audio X-12 subs. We use six 3" aeroports to reduce port noise so you get nothing but clean clear bass from your sub. Also, the subs are recessed 3/4" into the box. We use an internal brace as well as a double top baffle. All joints are glued and screwed together to insure that the box will hold up against the high output of the subwoofer for as long as you need it to.
