John,> I "mass load" them ... All loudspeakers are subject to the reactive forces of their larger drivers. <I accept that loudspeakers can vibrate as you describe. At the risk of sounding like a broken record, what specifically do you believe is improved from "mass loading" or any other such thing?> Number one means that as a wave is formed not all of its "energy" is translated into the movement of air. Some efficiency is lost. <Okay, that's a reduction in volume. Have you been able to measure that with a dB meter? > the rise time of the tone < Rise time directly relates to high frequency response. Have you measured a loss of high frequency response? All of the things you describe have parallels in known audio parameters. Nothing you have said so far can be ...
I've got some Magic Unobtanium Quantum Foam Time Decoupled Flux Enhancers for them.
QuoteI "personally" don't use spikes or cones under my speakers, I "mass load" them, so you have several different things at play. John can you please provide more detail on the mass loading. Are you slapping some 45 lb plates on the speakers? Seriously what kind of weight are you using and can you recommend where they can be purchased because I would like to give it a try.Thank youBryan

Wouldn't it just be easier to put some weight on speakers and try it, or put something under a player/amp and try that rather than debate this for 11 pages?
John,> I would gues that you could measure cabinet "talk", and I would guess that you could measure reasonances from a wood floor <I agree with that, and we're really not so far apart. All of the stuff you've mentioned seems plausible to me. Where we differ is the extent of the change, and whether it can be measured.--Ethan
