Looking at, per dealer suggestion, an MDF enclosure for this sub: http://www.wisdomaudio.com/products_sts.php
The install is to be inceiling, across 2X10 joists, with probably plywood between sub and joist. Is sound putty an adequate and good idea between plywood and joists and then what, if anything between sub and plywood-layed on its side and port pointing ro floor? The other issue is a proposed MDF enclosure port attached to the sub port and grill then attached to ceiling level end of the MDF. Any advice appreciated.
Thank you very much
