Yes, I have speakers in a square configuration except with the rear speakers elevated near ceiling level, stacked on top of other speakers from different amps and the front speakers on the floor. I prefer not to use A+B at the same time because it's more demanding for the amplifier but I'm probably being over-cautious. I suggest try out a few different combinations like the one that you have described: front speakers=SPEAKER A FRONT + SPEAKER B FRONT, rear speakers=SPEAKER B REAR,(resistors on SPEAKER A REAR). This would allow you to switch on/off the rear speakers without mixing the front/rear channel locations.
And How do You like the mixing two types of sound from diferent speakers at the same time?

Does anyone else have ideas about most suitable combination?

I'm finding my new speakers. I really like Sony ssg-??? and Kenwood kl-???. Does anyone have experience with this speakers?
Thanks
