My system is in a relativly small room. 14' across X 10' deep flat celing. I'm using an Onkyo TX-Sr605 reciever mated to a media pc via digital out. Speakers are Cerwin-Vega LS12 mains, matched center, and bookshelf speakers for side fill. sub is a XLS-15S by Vega as well. I know they are Vegas and all. But my problem is the peaks. The room resonates at two or three low frequencies. If i turn the volume down to avoid the peaks resonating as bad frequencies esp. voices are hard to make out. I can't find anyway to EQ the sound coming out of the computer and the reciever only seems to adjust for delay and speaker capability. Is there anyway to map a curve and apply an EQ filter without spending more than my whole systems worth?
