I hope you guys can help me once again.
I finally got the ASM-2 SPL Meter. Got all speakers set to 75db.

Should I use the meter to test the sub as well? When I try, the sub does not come even close to that. Even if I turn the trim all the way up. I can get it to only about 55db or so.
Is the spl meter an appropriate device to test the sub? I never felt like it was really quite as loud as I would like. Also what is the "Weighting" switch on the meter? Thanks guys.

My setup is
w22s
w150
qs8s
ep350 v3
denon 2809ci


PeachTree 65se, PeachTree D5 and SVS SB1000 - Stereo
M80s, M22s, SVS PB3000
