I find I need to keep the output level at a little over 75% of full output to fill my room with bass. I don't know if that will change with more run-in time. Also, my room is not very big.

I was just wondering if anyone else finds they need to run the output the way I do.

Thanks.

Just a thought, have you checked what the sub woofer setting in receiver is at, you should have an adjustment for the sub level. If this is set to low then you will have very low line levels coming out of the receiver and will have to compensate by having the sub level high. Most receivers will have -10 to +10 range of adjustment.
