What is going on with that? If I increase the sub level again in response to Gard's suggestion, won't this number keep going up because things will be recalibrated to this higher SPL?
|
Turn up the sub, calibrate REW and lastly reduce your "target" manually. This will put the target further below the actual measurement and will engage more filter recommendations.

Also, if I go with Gard's suggestion of raising the level and then filtering down the peaks, do I increase the level on the receiver or the sub?
|
Doesn't really matter at this point, you're just trying to set filters, not calibrate the final system levels.

BTW, it might be worth noting that in my attempt to set up the input level to the BFD, I had a of a time causing more than 3 LEDs to light up.

Were you monitoring the input level to the BFD?
Did you play a bass heavy movie?
Remember, the input level setup for the BFD is simply adjusting the trim level of the receivers subwoofer output in relation to the rest of the speaker levels. The main influence on the input level is of course the receivers main volume control that is at the mercy of how loud or soft you listen to your system.
Setting the input level to the BFD is simply an exercise to ensure you don't have an input level feeding the BFD that clips it when listening to a movie at its loudest level, and conversly checking that you have as high a level as possible feeding the BFD when listening to a movie at its loudest level. This simply means moving the trim level around a bit to have the most efficient level feeding the BFD.

BTW, I did some quick sweeps in different listening positions and I was surprised at how deep that dip at 63-ish Hz got in some places.

Wait on that one and see if your mains clean up the dip.........
