  GR Research Drivers and Rythmik servo amp.

  They are using 2 or 3 drivers per channel.

  I have tried 1 driver per channel and the output IMHO is too low.

  The servo amp needs the lower impedance of multiple drivers to generate the higher power and higher output.

  GR Research's 16Ohm drivers are really @ 12Ohms, thus you can't run 4 of them per channel with their servo amp. If they were truely 16Ohms, you could run 4 to get 4Ohms and could also get complete mechanical cancellation by running 2 against the other 2 in a W-Frame.

  GR Research has a forum on Audio Research that may help you out. They are also selling H-Frame Flat-Packs for 2 and 3 drivers.

    Thanks. That clears things up for me. I couldn't figure that out just reading the Rythmik order page for the CI OB part. I am looking to add bass to my 1.7 for classical and jazz at sub 90 dB listening levels. Many recordings are fine some not so much. I have had some significant improvement putting one DWM on its own amp and setting the amp's low pass filter to the internal DWM 'crossover' level of 200 Hz. I have to turn the DWM off or down for movies as it distorts from non-musical noise...like explosions. I have been reading up on articles on open baffles and other subs - SVS, Rythmik. Counter to the trend I would not want too much bass but I suppose that's just turning down the volume.
