Well, I have to say my experience with the Tact 2.0 RCS was less satisfactory.
Regardless of the correction employed- and trust me I REALLY worked with it, it still could not give me what my ASC tube traps provide. Now admittedly, I have more money tied up in tube traps than the Tact costs- but the Tact always pulled a bit of "life" from the midrange and slightly constricted the hall ambience (for want of a better term).
The thing did do some things wonderfully well, and the Tact 2.2 seems to be a better unit.
I've concluded however that the best way to tame an analog problem like room resonances/nodes is with an analog solution- like the intelligent use of ASC Tube Traps, RPG wall treatments and so on.
