I just finished my new theater room (19x14, 133" screen, two rows of seats) and am in the process of testing out the sound after running PBK and ARC. Just wanted to shoot a few questions out there and see what the general concensus is. My setup is Paradigm Monitor 11's, Center 3, Axiom Audio QS8 surrounds, and Paradigm Sub 25. My receiver is an MRX-700.
1) In my old room I only had one row of three seats so my 9 measurement positions were in a very concentrated area, allowing for both side seats to be within the sweet spot I created around my middle seat (main listening position). In this room, however, I now have two rows of seats (the second row is on a 12" riser platform) and no dedicated main listening position as I will be sitting in both the front middle and back middle seat depending on the movie genre, video game, TV show, etc I am watching. Because of this I am trying to create as big of a sweet spot as I can so all seats, both front and back, sound equally the same.
To do this I took a measurement at each seat in the front row, each seat in the back row, and in-between each front and back row seat, so 9 in total (front row, in-between front and back row, and back row). I also made the spot in-between the front row and back row my starting position as to create as non-biased a result (in terms of sound levels, etc) as possible for one particular seat. I also measured so that each speaker distance value is at the this middle point between the front and back row.
Does this sound like an appropriate strategy to try and create as big of a sweet spot encompassing the front and back row together as much as possible?
2) Is there any harm in bumping up any of the speaker trim levels post-ARC? Because I am trying to get the most even response among all seats, I am finding that the surround speakers are 2-3dB too low when sitting in the front row. Will any of the calculations/corrections be affected if I bump up the surround speaker levels a little bit?
Also, attached are my new graphs, both PBK and ARC.
The trim levels are:
Front Left +1
Front Right +1
Surround Right 0
Surround Left +1
