My right bass channel that that sited right next to the equipment bay has no bass. The left LF channel is sitting in a very good “hot” spot but the right is in bass hole. I would need 6-8dB of extra gain across the entire bass bandpass to have to work properly but Milq does not have these 6-8dBs. The bass channel have a strong room mode around 63Hz that severally mask any lower response.

Well, I kind of concern what to do with my very strong 63Hz mode. Surely I will try to put the bass channels in different position but I very my like the current position. What other options I have? Please do not insult my intelligence proposing the bass traps… I might consider but Helmholtz resonator tune for 63Hz but it will not work across the whole room. The implementation of a series notch filter would contradict my Macondo's Axioms and will affect bass’ tonal and dymick fertility. It is interesting that opening the large sliding good do smooth the 63Hz mode to practically acceptable level but it might not be considered as universal remedy.

So, I wonder what kind option I have. I think the most proper would be to reengage the Macondo's Axioms and to see how the bass channel might be modified in order to work alone with 63Hz mode but not against it. I think the rational proposal would be to divide my current bass to Lower Bass and Mid Bass and to have the deviation somewhere around 60hz. This way the lower knee of Mid Bass will be greatly stimulated by 63Hz mode but the upper knee of Lower Bass might stats from 38-40hz, playing with filter and allowing a the 60Hz region to be handles properly and with any peak. If the Mid Bass will be a horn then the 63Hz mode will work very nice and might punch the response to the lower 50s but with smaller horn.

I like the idea but I need to model this behavior with the actual room measurements
