to Sub/Mains Set Rear Speakers to Small and if you set LFE out
to Sub only set Mains to Small if you set LFE out to Both set
Mains to LARGE You can also set your MAIN LEVEL to Normal or
-10dB if your mains are too loud compared to center and surrounds.The crossover in the 995 is too high try setting sub
