Welcome! Need support, you got it. Or share your ideas and experiences.

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.

Exactly! That is what I was clarifying (poorly) from my poorly worded subject line previously. nt - DragonEars 18:05:20 03/04/15 (0)
