Since I have a baby issues I constructed a 1Mx1M MDF platform with spikes at the corners that is being flexibly bolted onto the platform so that I could actually rotate the speaker(since it's originally stands on the ball bearings) and it turned out to be the great tweak. In addition the speakers are loaded with 50lB of a lead shots
bolting speakers to floor?
i have a pair of gershman speakers, that are very top heavy (on thick carpet over plywood). i live in earthquake country. i've tried several spike set-ups and they still seem unstable. how will it affect the sound to drill through the base and bolt them directly to the subfloor?
