el 0l if you could understand the basics about how audio waves especially bass range acts in closed space you wouldnt even bring the name Bass EQ it just cures the sound pressure in a single spot(listener) and possibly can not do anything about ring of bass, and what we even hear is the constant  of Frequency over time which in playback audio describes as Q (quality factor) the most importance and usually  the most ignored aspect of room audio by DIGI EQ makers ... good to hear a breif note on audyssey website : ("Does MultEQ eliminate the need for acoustic treatment?" No. Although MultEQ will improve sound significantly in untreated rooms, a properly treated room calibrated with MultEQ can achieve stunning results throughout the listening area. ") I'm not ignoring the benefits we may get from it but actually A well treated room does not need any EQ

Unicon, I agree with what you say and not.

LF the digital EQ will flatten the response for a single listening location. It will do it with no problem. Will it result sonic improvement? This is more complicated question. Let pretend that EQ does not destroy sound by DSP in case it is digital and does not spin phase. Still, flat response is not the objective. I have seen in some rooms very un-flat response that did not affect listening. Some peaks and some dives in the response are fine – it all depends how wide, where, how they related to the rest of the room response and how they masked out. No one advocate running digital IQ to flat bass (it is not complex) but to use digital IQ discreetly, fixing the major problems I think would worth to explore. BTW, what you do is not much different – only you use resonating limp panels. I consider your way of doing the thing is preferable but you endure a lot of acoustic treatment in your room. If it is a dedicated or demo room then it is fine but I do not have an objective to have DEMO room, I am looking for to make it living room.

Frankly I think that my way to do the ROOM is more preferable: do not fine with room and do not treat the room but rather to design the accustom system around the specific room behavior. I admit that so far I do not have in my room success but I just started. I think the final result might use some of your limp methods but the EQ ONLY for LF doe not sound too absurdish as well. My problem not is not with EQ but with absent of ULF channel with which I would model some lower bass behavior. Again, the jury is out but I still would not put the treated room in the epicenter of attention.
