In the interest of sharing experiments with other Genesis users, I am posting my own changes.
I have a 5000^3 room that is open on side at back. 7.4 system with 4 sealed subs.
Level matched subs and adjusted gain for smoothest fr.
Ran Genesis beta with 5 positions adjusting height at maximum correction frequency of 5k
Used Radio Shack meter to adjust 3 speakers that topped out at +12. required addition of 2 db for surround and 1 for back. Then, specifically for our large room, added an additional 4 dbs to surrounds and back. This is the same change going back to Lexicon many years ago. In our space, makes surround float in the air. Obviously, this last change is room specific.
Adjusted High frequency roll-off at .88 on all speakers to match. Got this number from lowest number on all speakers.
Added Deep Bass Boost starting at 40 of 2, 4 and 6 on 3 profiles.
Tilt level starting at 500 of -8 on all profiles.
We almost always use Bas6Tilt, which has Bass increase of 6 from 40 and tilt level starting at 500 of -8.
Occasionally, when the content has too much bass, we use Bas2Tilt, which is different inasmuch only has bass increase of 2.
Have attached my Genesis bass & 500 Tilt pdf.
I would be interested in learning what experiments and preferences other users have.
