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?

As long as the evaluation includes the complete vibration control system I described above I would also welcome a comparison.

I would also like to say that I have nothing against Tom, either personally or professionally. I do not know him and I do not believe we have ever met in person. He seems like a very nice guy and I know he has been helpful to many Audiogon members in a number of different areas which makes him an asset to the audiophile community.

I do feel, however, that there is a general lack of thorough discussion on the internet and in many audiophile publications on the subject of vibration control. Typically, there is a trial and error methodology that is used by most audiophiles and is also sometimes recommended by manufacturers and dealers – add the device to your system and see if you like it or not. We live in free society so no one can tell another person what they like or don’t like (and, of course, people should like how their systems sound), but this haphazard manner of evaluation is fraught with difficulty and many times leads to erroneous conclusions.

I think that we would all be well served by the introduction of more science and more stringent evaluation to the category of vibration control. This will advance the state of the art of audio reproduction. The most important issue is to understand the nature of vibration, how it affects the components within our systems and ultimately, how well the devices, materials and methods that are used address those issues.

Barry, I agree with you, and I'm really pleased to see that you have some testing charts and other documentation to help people understand the need for vibration management in their audio and video systems.

I always read your posts, and I also feel that you are a valuable and welcome member in the audiophile community.

Anytime more solid information comes into the public view, it is better for all of us concerned.

Even though we compete in a way, for certain segments of the market, we are both advancing the position of vibration management systems in the audiophile world.

We're working on getting some impartial 3rd party scientific testing on our products done at a major engineering university, and when we get the results, I'll be sure to make them public.
Barry is there any information on the speed or rate of vibrational dissapation of materials such as those in your designs versus the reloading or buildup of vibrational resonance in a typical stand alone audio component..Tom ..I sell audio and video products, some are sourced from Starsound..
