Speaking of cabinet resonances and vibrations. I have never put weights on any of my audio equipment. Reading many years ago that if you can balance a nickel on edge on top of your speakers and play at very loud volumes and not have the nickel move, you're good. So, of course, I tried it, much to my surprise the nickles never moved. That's with 24" woofers and 1.1kw of ARC power going to the woofers in a tri-amp system. Left the nickels there for weeks and finally got tired of looking at them. Try it, let me know. Regards, Barts
