My TACT can produce a pretty much ruler-flat response from 20Hz to 16Khz in my room with my system - but I prefer a gentle roll-off from 14k up of about -2dB. I don't agree there is anything magic about 200hz or how well DRC works above/below that. My experience has been very different from those

Don't get me wrong...I'm assuming that the room is not already crippled by uncontrolled RT60 etc. Of course DRC can't compensate for the walls/floor flapping around. So, really the room basic mechanics need to be OK - then DRC can work its magic with regard to freq/phase/image response. The prob

If you do not have a room problems with standing waves then you can not appreciate what the room correction does. Also it must be done properly, not too much corrected because it becomes sterile, and test multiple target curves. I have a 9dB boost around the 130hz area, imagine listening to that
