Spikes versus wall coupling


I have a Polk SRS-SDA 2.3 speakers. They are 185 lbs each and currently sit on thier furniture glides on a maple floor, over subfloor, over trusses. No carpet. They have a passive radiator for lowest base at the bottom of the cabinet, and I roll to a subwoofer at 60HZ. I like to move them occasionally so have been reluctant to use spikes.

My question is what am I really missing sound wise? And would wall coupling do as well as spikes. I can put them on some marble slabs,as another alternative, or remove the glides and have the bottom fully sit on the floor, o rthe marble. I do not have a turntable. Or should I spike them despite the hassle?

So this must be why when someone runs next to me on the beach, I can feel his pounding footsteps in the sand under me.
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?
Ok, I'm an employee of Starsound Technologies, and I asked the question about the sand.

Actually, I felt that I was being remarkably silent, considering all that was being stated here.

Truthfully, the reason why I was(and still am) at a loss for words here, is that I wouldn't even know where to start addressing all of the things mentioned on this thread, except to say that I'm not in agreement with hardly any of them.

I'm just letting the guy say what he wants to say.
I work for myself and for my clients. I sell products that I own myself, some of them are sourced from Starsound.Tom
TWL I was the one who started this thread and I would love to hear what your ideas are on vibration control. No need to response to Barry or others point by point, rather just give your feelings on the best way the deal with 185 lbs speakers on woood floor to get the best sound.
