This listing is for a custom ported enclosure for a 15" Alpine Type R Subwoofer.  We use two 3" aeroports to reduce port noise so you get nothing but clean clear bass from your sub. Also, the sub is recessed 3/4" into the box. All the 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.
