what I really did is that I really turned off the power switch of my sub when my speakers were set to small (and a crossover of 80)

But in my AVR menu I have 3 options for BASS
- both (speakers + sub)
- sub
- none

I currently use BOTH and turned off the sub via the power switch.No changes were made on the AVR.

I will try your suggestion as soon as I get home (can't wait)..
