Spikes versus wall coupling

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.

Hi All,

Anyone interested can see laboratory measurements of a speaker system with and without the vibration control system I described.

Here is the link:

or

Figure 1 shows the frequency response of a speaker without the vibration control system (red line) and the same speaker with the vibration control system I described (black line). You will notice a significant increase in response with the vibration control system.

Figure 2 shows a Cumulative Spectral Decay (waterfall) response of the speaker that is not placed in the vibration control system. Note the significant amount of vibration residue the speaker exhibits. This is vibration and resonance that is absorbed and released by the cabinet walls after the drivers have stopped producing the original signal. The extra "ghost" signal not only significantly colors the music it also produces random out-of-phase elements which affect imaging, soundstage abilities and transient response.

Figure 3 shows the same speaker that has been placed within the vibration control system. You will note that there is far less extra residue present in the speaker system and the graph looks much "cleaner". The extra energy that had been wasted making the cabinet vibrate is now being used to create more music - increasing efficiency and performance in all areas.

Figure 4 shows the same two waterfall graphs together
so you can more easily see the differences.

Please let me know if you have any questions.

Best Regards,

Barry
