I am planning on purchasing a bunch of Auralex products, some for absorbtion some for diffusion, namely their AudioTile Shockwave, TruePanels and SpaceArray diffusors.. I'm hoping that will address my issues, ie: lack of bass output in most areas, echos / ringing, quick high frequency rolloff..as measured with a RTA.. I have done over 5 months of researching and some "professional" measurements..previous post are in here..I have not ordered it yet..but the total package will cost me $3,500 CA.. sure hope I can tell a significant difference in overall sound quality..:-) I will post some pics once completed.. ETA is late August.

Cheers,

Steph
