So got the Scosche SPL 1000.
Did the leveling to 75 Dbs.
Huge difference Audessey set levels to minus levels, after the SPL meter I've set all to plus 5 or 6. Haven't noticed any limitation from my A.V.s max volume (Tascam PA-R200) it's 100 watt RMS Torodial 7.2. Should I be worried of clipping though haven't noticed distortion at all yet.
