"However I am adding an image of exactly what the circuit does."
'Thanks! Couple of things, though.
Looks pretty good (numbers on the dB axis would be nice). But I wonder, given that our ears work like integrating 1/6 (IIRC) octave filters, if the broader lower rise isn't still audible compared to the sharper higher orif=ginal peak.
Should mention that something's funny about the graph, though. At the edges of the peak both the blue and red lines are negative, so how could they combine to positive (yellow)?
Thanks for the (quick!) answer on the lowest correction freq. I'll just say I think it should go down to at 20 Hz. My room is 22' long, giving a first mode at 25 Hz, and I'm sure there are people with bigger rooms.
For reference, 62.5 Hz will be the first mode for a room with an 8.8' largest dimension.
If a change in MCACC to address this isn't forthcoming, I'd at least be interested to know why this limitation was placed on the design.
Thanks so much
