I am interested in purchasing a Clark transducer but would like some feedback from anyone with one or more. Do you have it in furniture or mounted to floor joist? How much power and what kind of power? When I had my house built I oversized the floor joist in the theater area so the floor wouldn'd move.I was thinking the floor joist to keep it out of my wifes view(what she dosen't see wont hurt),does this give good results or should it be in the furniture?
