Hi everyone, I tried my friends' Acoustic Images several times(don't own one yet, hopefully pretty soon ) and like them. One of my concern is, and, of course many of users reported, that AIs sound totally different where they are placed on. Wooden floor, concrete, on the carpet....so on. Today I was thinking like, there is a product called Auralex Gramma(is it right??) on which you can put your amps to isolate the amp from the floor, so what if someone put an AI(or anykinds of downfiring cabs) on top of Gramma?? Maybe your AI's sound will not be affected by floor that much and you get more control of your sound I guess?? Or it will just kill the advantages you'd get from downfiring amp?? I was just wondering. Anybody tried?? Or anybody has both of them and willing to try??
