I have a laptop running windows seven, REW already downloaded, Behringer u-control uca-202 which I may not need, and a Extech 407736 SPL meter. First will my SPL meter work?? I have the Behringer ecm8000 ordered, but what other gear and wires do I need? I want to calibrate my dual subs, I currently have a Integra 80.2 with Audyessy multieq xt32 but would like to dial them in better. Sorry if there is already a link for this information I just could not find it.
