I gotmy PE 250W plate amp today and also my SPL meter and want to know if I did this correct. I just went ahead and used the receiver internal test tones for calibration. My equipment: Kenwood VR505 HTD Level II Speakers (all the way around) 20-39CS SVS with a 250W PE amp I set the SPL to 80db for readings for all the speakers. Then I set it to 90db for readings of the subwoofer. Is that correct? I read through the SVS website and this seemed like the way they had recommended setting your sub. I wanted to set the sub higher for the extra bass as the SVS website claims. Also, when adjusting the subwoofer to get to the right of 0db on the spl meter, should I be adjusting the amps volume or the LFE control (it's -10 to 10 on the VR505). Thanks for looking.
