Hi,

My room size is very small 11' X 12' and I am useing Dynaudio Contour 3.3 in it. Now I am having some boom problem, useing bass trap does'nt cut it. So I was thinking of buying some room tunung devise. Does anybody has any idea how good is those Harmonix Room Tuning Device, I am getting them in half price. And one more thing does any one has any idea that, is it going to really help me or not. As even in half price it is a expamsive thing.
Abt $ 400 for 16 pcs.

rgds,
