Does raising speaker cables off the floor really make a big difference?

geoff,

I may have missed the post to which you are replying, but are you talking about isolating speakers/subwoofers from the surface on which they sit?

Can you clarify why you see it as easier to do so with a subwoofer?  Do you mean perhaps that a taller main tower speaker may become more "tippy" when you try isolation underneath?  


Not challenging your claim, just wondering about the details.

The reason for “isolating speakers” is not really to prevent vibrations from the floor being transmitted to the speakers, although that would occur, it’s to prevent the vibrations from speaker cabinets being transmitted to the front end electronics via the floor (mechanical feedback). Isolation systems are two-way 🔚🔜 systems, as illustrated in that Townshend YouTube video - they attenuate vibrations in both directions! 

I suggest isolating subwoofers for two reasons - (1) they are easier to isolate and (2) their frequencies are lower than speakers and do more damage potentially. In a perfect world everything would be isolated - cables, power supplies, DAC, solid state amplifier. The reason speakers with high center of gravity are a problem is that springs under load lack sufficient later support unless the springs are placed far apart from each other in a wide pattern. That wide pattern of springs is much more stable. Small springs are more stable than taller springs.

Some of the tweaks do make a difference although me myself have not heard one that made a big impact. I prefer to upgrade a component first before tweaking my system. Like installing a simple AC filter choke that so far has worked in every component I have installed one in, but that is just me.

Happy Listening.

Ok, I found the big difference , when I raise the cable . and get two shots
Stolichnay , the best Russian vodka , sound became 3 dimension 

I noticed a small difference. Dont spend money if u can at first. Use paper cups or whatever to test it first.
