As you know the OS are so large even having them back to back is not quite what I would call co-located. It really smoothed out the whole room's bass response vs 1 OS. I would say 2 OS's took me 75% of the way there and 3 got me to 90% even room response. The time delay may be the single biggest factor and improvement by adding the minidsp. The only issue I have with the 2x4 balanced is the time delay max between outputs is 7.5ms which isn't quite high enough. Some of the other models don't have this limitation. How big is your room?
lbrown105 I have followed your posts, I lurk on the jtr forum most every day. Room difficult to explain, a general living space open in spots on one side heading different directions, hallway, kitchen, downstair. Ballpark 32' x 20' w/8' ceilings.
Very encouraging to hear your results regarding adding a 2nd OS!
The only measuring tool is spl meter, the omnimic V2 has shipped so it should arrive later this week.
OS is corner loaded in rear left corner, have a spot to corner load the second OS in rear right corner. Not short of bass IMO, could use a little evening out. Without measurement tools no way to know what I have going on.
Same LCR as you, surrounds are 228's. Converted to jtr earlier in the year from Def Tech 8080 LCR & 8040 surrounds and a brief run with legacy focus SE speakers. The jtr stuff is really strong.
I've heard the minidsp open drc an is a possible solution for bass mgt after running xt32.
