    I have a wooden floor and a downward firing sub.
    I dont have it too loud.
    I've heard people saying you should put subs on one these.
    Would it make a differance in sound?

    Hi,

    I can't rate mine highly enough. I use a Velodyne SPL 1200 which is a forward firing beast on a laminated wood floor. The Gramma stopped 95% of room and floor vibrations, and seemed to tighten up the bass.

    I am not sure how effective they are on a downward firing sub? Good luck.

    Rob

    Don't know if the Gramma is any good for downward firing subs,
    I use a 25mm thick slab of marble and it made a big difference.
    Would be interesting to find out if it is suitable for a downward firing sub though.
    Regards
    Daran.

    PS I'm a huge fan of AURALEX brand of products, dose exactly what is says on the tin
    :D

    One of the reps said that he didn't think they would be much use on downward firing subs and I have no reason to disbelieve him

    Why? I don't quite understand why this doesn't hold up, or am I being stupid? In my experience downward firing subs transmit just as much resonance as front facing ones? Or is it something to do with the gramma deadening the bass itself? :confused: :confused:

    Gramma' s do work just as well with downward firing subs,

    Adzman is using one with his Mackie with good results. :)

    I tried one under my [downfiring] ATC Concept 4 sub (great big £2K beast of a sub), with my suspended wooden floor, and it definitely cured all the vibrations and rumblings that plagued my room. Can't say for sure if it improved the sound though. I thought it was maybe a bit tighter and cleaner, but it was subtle enough that it could've been all in my head. :)
