Does a Auralex Gramma pad make a difference on a concrete floor?

    Most of the clubs that I play in don't have elevated stages, just an area on the floor. I'm just wondering if anyone has noticed, because doing an A/B test by myself would be tricky. If I would ask any of my bandmates to help me perform this test, they would just give me the stink-eye and whisper things when I'm not looking. I can see how it would make a big difference on a wood floor or stage, but on concrete, I'm not so sure.
     
  2. No, it shouldn't. The idea behind the GRAMMA is to decouple the cabinet from the surface. The concrete isn't going to sympathetically vibrate with the cabinet.

    That being said - I still use mine on pretty much whatever surface exists where I'm playing. Even having them two inches higher is something I like, and to me (subjectively), the cabinets tone is slightly tighter and more "clean" having them elevated (even a little bit) off the floor (I'm sure there's something mathematically significant with the way the sound waves reflect off of the floor).

    Over to the engineering crowd...

    Actually, just like Jay, I do the same thing and use it on any surface. I too believe that lifting it up a little helps, and I'm sure it helps me hear just a little better.
