Thanks for any info
For a makeshift riser, most people seem to be using 0.5" to 0.75" plywood, and those BK are good isolation feet to start with. I installed 0.75" pine plywood under my loveseat with a pair of Crowsons, and just ordered a couple of ButtKickers, and it works wonders for directly transmitting tactile effects. Perusing AVS, I've read mixed reports though on how helpful such a "mini riser" can be when only subwoofers are providing the main source of tactile energy. I'd probably shy away from using baltic birch for this purpose or making it too thick/rigid, as a little flex is necessary.
Do you run or intend to add a tactile transducer? Concrete floors and a couch on a plywood riser (with proper isolation feet) are beckoning for the additional bass reinforcement that bass shakers or motion actuators can provide.
