Some food for thought there Bob. I read the Lipinski review and their specs. Great review and the specs are astounding, almost unbelievable. I would like to see lab tests. I took a look at digido also. I am wondering how can your Lipinskis be down 10dB at 16K when their stated spec is 56Hz-20kHz ±1dB (31Hz-40kHz ±3dB). I acknowledge your points about how rooms alter things but in a reasonable RFZ at short distance, on axis, I normally get mid and upward curves that are very close to the anechoic ones from the manufacturer. Did you measure with one or both speakers driven? They will fight when trying to combine at a single point measurement mic.
I have mislaid the PMC measurements in my room but I can clearly remember they were astonishingly flat, but remained so up to the measurement limit. No roll off.
I note your speaker stands are firmly tied to the concrete slab. Are the speakers then resiliently mounted on the stands, sitting there, or bolted on? ( Speaker stand theory is another one of my hobby horse puzzles. )
I do hope you get the PMC's in for a trial, and if so, please do let us know how you get on. I reckon it will be a difficult shoot out. Fwiw my old reference speakers, the Ditton 66 have a soft dome mid, a bit like the PMC's. Klein and Hummel do this also, and I like all of them. Could be familiarity but for me there is something uncannily real and different from all other speakers when listening to human voice coming from these domes.
