Auralex Gramma

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.

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.

Daran.

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

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

Thought so ,
Thanks Ian.

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?

thanks.
I'll find something else to spend money on then

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.
