Using different ouputs for two different drivers

john dozier · 10th October 2011, 12:02 AM

Is there any advantage to using two different OPT outputs to drive the woofer and tweeter in a two way designed for bi-wiring? I would like both opinions and real world experience. Thanks

Which OPT secondary would provide the negative feedback? No nfb means high output impedance which destroys any possible tiny gain from bi-wiring.

There is some info in the RDH4 on pages 185 and 887,888 on frequency selective outputs. Seem rather complex for any more than 6 dB/octave crossover. Any secondary feedbacks would have to be frequency tailored too.

The amp in question is a No NFB design. I am concerned about other problems though. Thanks
