I don't want to hijack this thread as my original question was about how hot the Ref 5SE runs.
I want to correct a few things here. JL Audio f113 single-ended input impedance is 10k Ohms (balanced unspecificed). But the f113 sub was never connected directly to Ref 5SE but to Bryston 10B-SUB active crossover.
So here are my connections:
Ref 5SE ====> Bryston 10B-SUB XLR (impedance=20k)
10B-SUB low pass ====> JL Audio f113 (10k or 20k unknown)
10B-SUB hi pass ====> McIntosh MC452 (22k)
I've tried connecting Ref 5SE directly to MC452, then f113 to MC452 output, that means only one set of REF 5SE output used. There is no difference to 5SE running temperature. But I noticed less background noise.
