Spikes versus wall coupling

Personally I would not advise spikes. Why would you want to couple these speakers to a wood floor. In fact, with the mass of these speakers they are already more than adequately coupled. In my view you should want to isolate them from the floor, if anything, so you don't have to listen to the results of floor vibration any more than necesary. FWIW, I can't think of a single reason to couple speakers to a wall.

Now don't laugh too much at this suggestion, but you might consider using some hockey pucks and some felt pads on the bottoms of the pucks. That way you get some isolation and still have the ability to move your speakers about.

With your speakers I'm afraid the mass would compress the felt so much that it would just become another mudium for transmission of vibrations. Cork could work and those dense rubber mats sold at Home Depot combined with some felt so you can push the speakers about could also work. Not necessarily elegant solutions but probably as good as most. IMHO most of the vibes from speakers that are really destructive are air borne.

Tom, If you want to couple speakers as massive as these to the floor why would you need to do anything except let the wood bottom rest unobstructed to the wood floor? That would certainly allow all of the vibrations to pass directly to the floor. In fact I think a case can be made for the proposition that if you insert an intervening devise you might successfully limit the vibrations that may be transmitted from the speaker cabinet to the floor to those vibrations that the intervening devise can pass. Assuming that the devise is not limiting, how exactly will it improve the direct contact of the bottom of the speaker?

One last question, once you have all of the vibrations being transmitted to the wood floor, if you have similar devises under your TT and equipment racks how to you keep the vibrations from going up into the TT and other sensitive components in you rack? Or do the vibrations only flow in one direction?

I agree with TWL, except I'm never at a loss for words. I think this thread is a vintage argument for the old saying what ever works for you must work. There are just so many theories regarding vibration control it's tough for folks like Gammajo and I to know what might work for our systems. Some one sez that spikes couple but cones isolate. Dense rubber couples. Lossy rubber isolates. The difference is(?) the mass of the speaker/stand. Who's to know. Then there is the "drain vibration" school of thought, which makes sense to me if you are talking about draining vibrations from a component which are exciting it's resonance frequency, but how do we insure that the materiel used to drain off this resonance actually passes the resonance frequency, and what happens when the devise actually hits it's own resonance frequency. Then there is the issue of vibration/resonance amplitude. At what point do these vibrations and resonances become audible significant?

Wow. Poor Gammajo has no more a solution to his question now than when he first asked his question. :-)

Gammajo, Thank you for your recommendations. Since you bring up Volados, I would most highly recommend to you his Schubert solo piano works on Sony. This is not only outstanding playing, an excellent recording, but who would ever have guessed that Volados could play such sensitive Schubert.

On another matter, you teach mediation - I'm on the other end, utilizing mediation extensively to resolve civil litigation cases before trial. Great system and tons of fun for those who are or would become skilled negotiators (you've added another person to the mix who requires more attention than the other side!). Keep up the good work.

TWL, Maybe its because the sand is wet? Did you consider that. Your friend should loose some weight, for his health sake, if nothing else. :-)

BTW when you and Tom are asking these kind of questions and/or making observations about a competitors products, don't you think it would be fair for you and Tom to once again identify for the uninitiated who your employer is and/or what products you sell?
