I finally had some time to take some measurements and run the ARC software for the first time yesterday.
I have an AVM-50/ARC with a B&K Reference 200.5 amp powering the following:
Mains - Martin Logan Ascents
Center - Martin Logan Stage
Rears - Martin Logan Scripts
Sub - Martin Logan Descent
The actual room is 16' W x 13' D x 9', but the room opens up on the right to the breakfast nook and kitchen. Basically, the theater is not in a closed off room at all as there is an opening to the main entrance and a passageway to the formal dining room in the kitchen.
In looking at the results, I have about a 5db drop off at around 65-70hz that ARC was not able to correct very well. The mains drop off considerably at 12-13khz and the rears drop even more starting around 1-2khz. The performance of the rears probably has a lot to do with their height. I think I could get better result by lowering the speakers or somehow pointing them downward.
Any other ideas that might help with the drop off at 65hz (it effects the speakers in the front of the room, but not at the back of the room)?
By the way....I set the ARC to max at 10khz. The auto detect set the following crossover points:
Mains - 40hz
Center - 95hz
Rears - 85hz
Sub - 120hz
Room gain was about 3.9
The results of this measurement further substantiates my desire to go with a different speaker system (been eying Paradigms for a log time).
As far as results, I can't say for sure yet as I haven't sat down to a movie. I can tell that dialog seems clearer and I have more energy in the surround speakers. I look forward to putting in a movie soon.
