This listing is for a custom enclosure built for 4 Rockford Fosgate T1-10 subs. We use 4 4" aeroports to reduce port noise so you get nothing but clean clear bass from your subs.  Also, the subs are recessed 1/2" into the box.  All joints are glued and screwed together to insure that the box will hold up against the high output of the subwoofers for as long as you need it to.
