I have a 18x18 square room.
Integra pre-pro with Audessey 32x.
3 subs. Spaced evenly across the front of the room.
Center Elemental Designs A7s-650
Right SVS PB-12 Ultra/2
Left SVS PB-12 Plus/2
I ran Audessey.
Then I ran the SMS-1
I have a pretty good dip right at 50-60hz.
Audessey set my main speakers to 40hz, so I am thinking
this might be a phase issue.
While the SMS-1 is running I go over and turn the phase on the plus/2
about half way. Flat as a pancake. I try the phase on the Ultra/2 and it
does NOT do the same thing. I did not mess with the phase on the ED.
At this point the sms-1 has no adjustments at all.
Is this ok to do? What other issues am I introducing here?
