Violet- Good to hear from you. I totally agree. Just haven't gotten around to dealing with that yet. Will probably use some sort of spikes.
Gammajo - I was told they worked best between the modules as that is where you want decoupling to eliminate distortion, whereas between the bottom modules and the floor, you actually want to drain the excess woofer energy through the floor. In that case, points or something similar would seem to make more sense.
