Right, lewm, and that was my objection as well. Problem is, the speaker is going to move and vibrate anyway. There's no stopping it. Its not just the drivers going back and forth either. The drivers create pressure changes inside and outside the cabinet, this gets the whole speaker cabinet vibrating like a balloon with air rapidly being pumped in and out of it.
All this vibration is going on no matter what we put the speakers on. Even if we take the kenjit approach and mount them in 80 feet of solid concrete all that does is change the frequency and amplitude of the vibrations. Nothing ever really gets rid of them. Can't be done.
But if the speakers, or anything else, is rigidly on the floor, well then those same vibrations transmit a lot more readily into the floor, and the floor gets excited and vibrates, and those vibrations go everywhere. Some of them come right back up into the speaker causing it to rock slightly. This produces the ringing you can see on the seismograph in the Townshend video. Some of it also goes through the floor, the rack, and all the way to the turntable.
I thought no way this happens with my 750 lbs rack of solid concrete, granite, sand bed, and BDR carbon fiber. But it does. Proved that by putting springs under subs and hearing the midrange clean up. Only way that can happen is what I just said.
So its like I've been saying all along, its about vibration control. We can control it one way with cones and mass and rigid solutions and that can certainly help sound a lot better. But we can also suspend things that vibrate in a way that lets each thing vibrate in its own particular way with less of it feeding into all the other things we have that are vibrating.
All this stuff is vibrating. Put your hand on a speaker cable while playing music some time. You will be shocked how much it vibrates. Especially if there's any bass. That's probably why the rubber band trick works so well. Its free. Try it and see.
