    Building the better mouse trap....errr, IB

    A friend asked if I would help him with an IB enclosure. Never having dabbled, I was in. He is getting 2 Dayton 15" IBs and a plate amp from PE.

    He wanted to install it near the floor behind his mains. The storage area behind the wall is ideal. Standard framed 2x4 construction on 16" centers. No problemo.

    To keep the installation as simple as possible, I decided to incorporate a bracing/frame into the design. This frame would be installed first, from behind the wall, and the sheetrock could then be cut out by following the inside of the frame. The frame also sets the height off the floor for the manifold opening. Painless, so far.









    The manifold is 1 1/2" thick plywood construction with a single layer of ply at the front so it can slip into the frame. Since the drivers could be mounted from the outside of the manifold, facing in, the driver installation should be easy.

    Since the back of the manifold needed to be supported, I decided to extend the second layer of ply past the bottom and install leveling legs. After the frame is installed, all he has to do is slip the manifold into the opening, adjust the feet, and pop the screws in thru the front to secure.

    The grill is made from 3/4" MDF with a 2" frame. To secure the grill to the manifold, I bought 1/4" x 1/2" long rod magnets. Bored 4- 1/4" x 1/4" deep holes in the back of the grill and epoxied the magnets in. I then drilled 5/16" x 3/8" deep holes on the edge of the manifold. Into these holes I predrilled and screwed in 1 1/2" flat head screws to act as adjustable "stops" for the rod magnets. So, depending on the thickness of the fabric he'll use, by turning the screws in or out, the grill will stay put.

    Many thanks to Tom for fielding questions, as usual.
