I used rubber under my home theatre speakers (Athena s3/p3) and the sound was awful, affecting the bass the most.(bloaty, slow, and absolutely no punch, kinda like: bbllaaahhhhh) I used big heavy cones, and the improvement was immediate. Sorry, I do not recall the brand.
Spikes versus Rubber on wood floor?
I am awaiting a pair of new babies, the Von Schweikert VR4SR speakers. They will be positioned on a wood floor over trusses. Anyone have an idea if spikes or some rubber isoproduct will give me a better sound? Any brands of either that you would recommend? Thanks.
