I'm getting my home theater off to a slow start but it's coming together. I have two Klipsch SB-1's that I am using for fronts now but I plan to make them surrounds later on this year when I finish my HT. As far as Subs go, I just got a Yamaha YST-SW315 and it should arrive at my house within the week. My question is, would it be good to use AVIA and my SPL meter (radio shack) to calibrate my speakers and would the test tones in AVIA be benificial since it's really for 5.1 systems? I know it's only stereo but I would like to have the best sounding system I can until this fall when I finish everything up. Any suggestions on what to do (including any little changes in technique for calibrating) are needed would be greatly appreciated. Thanks.
