Zitoun,
Thanks!
I have not heard the Otica MTM to comment on differences in sound.
The BG NEO10 and GR Neo3 planars are the same as the drivers used in the Super 7.
The Monoliths use the 16 Ohm OB version of the 12" servo subs with Rythmik HX300-12OB servo amps with the 2x12's. I believe the Super 7's use the Rythmik A370PEQ and 8 Ohm OB drivers. The Monoliths with the DSP crossover need a balanced input servo amp.
The dspMusik or dspNexus can be reused in the system for other speakers digital crossovers, but I would have to develop a Super 7 crossover, and I do not have them to measure to do the digital design.
