Auralex actually makes risers/decouplers for mains

Eh, I just added spikes to my mains (Polk LSi 15's) to couple them to the cement floor. Cleared up a bit of bass for me and was a bit cheaper than a Auralex pad and harder to see I did...
What's your objective?
Do you have an issue that you want to correct?
Do you intend to couple or decouple your speakers?

Do you have a link, because I've looked at everything they have, and they dont have anything near the $39 except the GRAMMAs themselves, unless you mean the sonolite panels?
These things are the easiest things to make. I just used the elastic hi impact foam that came with the packing with my sub.(it's the foam thats bendable like rubber but has lots of air pockets much like the swimming pool water foam tubes)
I cut out some 3/4 inch finished ply and bought a black carpet mat from the dollar store for 6 bucks.
Just cut out 2 strips of the foam just to overlap the with of the sub at both ends and place the carpet covered ply over the strips of foam and just place the sub on top.
The difference at least in my room is a that the sub plays louder more rumble....if it sits directly on the carpeted wood floor it plays quieter but rattles more and the bass is not as defined.
I don't have a meter but im guessing i gain about 2-3 db in sound? It sounds like the gain would be in the 30-50 hz range?
Has anyone done some tests with these things because they do work!
I will have to make another one when i get my HSU 15h! I hope they pack that puppy with plenty of that foam.
