“Little by little, one travels far.” – J.R.R. Tolkien TLDR version: JRR is right. The many small things were: loose binding post nuts on the cross-over PCB (Left speaker), Left channel volume of the integrated amp is 5-7% lower across the spectrum, end-to-end speaker cable resistance for Left...

Thank you! Brief responses below "But the same thing can be done by having measurements of each channel separately and using arithmetic in REW" I did not know that, I will learn how to do this. :T "The hole at 250-500 hertz disappeared. But the correct polarity is the same as in the first...

Thank you, your advise is greatly appreciated. I did only reverse the the mid/tweeter (the bi-wiring makes that straightforward). The bass was left at normal polarity. OK. I can try that and post the results here. My original measurements above were done individually, on axis @1M. I configured...

Thank you @sm52 I did take a measurement of the left channel with polarity reversed. My system is bi-wired, so that made the task more straightforward. See below and attached. Additional Thought / Question: from my original post above, which channel has the expected phase response? I assumed...

- 2 Channel HiFi system, the left channel has a dull high frequency response that is audible - the SPL response doesn't show the problem (interesting) but the Phase response does - I physically swapped the speakers (L<>R) and remeasured. The phase response measurements follow the speakers So I...
