Ok I have a little bit of bad Bass waves in my room and find calbration difficult due to a bouncing SPL meter needle. I have 2 SVS25-31CS+ with port tune installed running off of a Sampson1000 to a Denon2802 receiver. Should the Sampson be all the way up and just cut the Denon's DB down to an average of the bouncing needle? It was so easy with the speakers but that damn needle will not stay in place. I was watching TitanAE last night and it was crazy loud!! The ice scene was freaking nuts I thought my room was going to explode, but yet again no bottoming out. It still worries me though that my sub may be overly hot.
