I'll offer a slightly different take.
Room effects are almost always most pernicious below app 150hz. Room correction in this range - IMHO - will far outweigh any benefits you get from maintaining a purist signal path. As you go upward in frequency, different rooms will make the cost/benefit equation of DRC vary enormously.
My solution is a Velodyne SMS-1 sub controller (room analysis + PEq below 200hz - coupled with a versatile x-over) and a pair of subs. You can keep the SMS out of the signal path above the x-over point, if you so choose. In my book, this as close to a "have your cake and eat it, too" approach as you are likely to find.
Caveat: In some rooms full range DRC may well be worthwhile.
Also, my understanding of the TACT/Lyngdorf approaches is.
TACT: Goal is flat response at the mic position (i.e. corrects for anomalies in the speaker frequency response and room induced frequency effects.
LYNGDORF: Goal is to preserve the speaker's frequency response & remove only room effects. You measure the drivers up close and then at the listening position. The software filters the difference between predicted (anechoic?) response at the listening position and actual measured response.
This explanation came from the folks at Lyngdorf.
