Basically plug and play. Mark has all the DSP/active crossover magic built into his Cats since he went the powered route. It keeps things relatively simple, although it does make implementation a little more difficult since each speaker needs to be plugged in. Basically if you want active or don't mind active, the Cat 12C's are there for consideration. If passive is what you want, you got the JTR's. That's were the M2 benefits IMHO. No amps or anything in the speakers, but still has DSP and active crossovers built into the amps OR external processor. Maybe in the future, speakers will be shipping with external processors with these settings built into them. Just adds one more piece into the chain of electronics so it shouldn't complicate things too much.
All else being equal, active has the advantage over passive, so I agree that's a big point in favor of the M2s and Cat12s (which I also haven't heard.)
JTR crossovers are the size of phonebooks, though. With some help from some good DSP, I wonder if that mostly closes the gap. I know it sounds good to me.
One thing that surprised me at the Kansas City Crawl was that none of the JTR speakers there sounded nearly as nice as mine do to me. No offense intended in that. I can't touch the bass I heard (sadly), but it left me scratching my head. It sounded like a more peaky response and in some cases it sounded more harsh to me. The closest was dlbeck's theater, which sounded smooth and neutral, but lacked the intoxicating quality that I'm getting.
Interestingly, when we listened to his Salks with RAAL tweeters in his music setup upstairs, there was that intoxicating treble. My reaction was, "That's what my 212 treble sounds like!"
Looking at the measured frequency response in most of these theaters, I can see that I wasn't imagining the peaky aspects to the sound.
I want to make sure I don't lose that intoxicating sound when I finish out my theater, so I'm trying to figure out what the deal is. My theories:
1) I spent a lot of time dialing in the target curve with Dirac to my taste. Maybe I tuned it to sound good to me, and the other theaters were tuned to sound good to their owners.
2) Maybe Dirac just does a better job correcting the frequency response then whatever those theaters are using.
3) It could be at least partially an amp thing. I know that is a questionable claim, but I really enjoy the pairing of the JTRs with my Parasound A51 amp over the other amps I tried with it. It seems to make the treble more pleasing. This difference is more subtle, and I wouldn't bet my life on it, but there ya go.
4) Maybe it's because I have a larger, more reflective room, and the intoxicating sound is from more lively reflections. Dlbeck's Salks were in his living room, not his heavily treated theater.
