Front L/R: Paradigm Reference 300 Series
Center: Paradigm Reference 30 Series
Suround L/R: Paradigm Reference 20 Series (not hooked up yet, soon to be)
Back Surround L/R: Paradigm Reference 20 Series (not hooked up yet, soon to be)

BTW, I had an old firmware version (3.7 or something). I am installing the new one as we speak.

Thanks,
