    Does a PBN M2!5 SHARE DNA with the M2?

    PBN speakers seem familiar, for some reason. Website mentions charge-coupled xovers and Symmetrical Field Geometry woofers. https://pbnaudio.com/m25-loudspeaker/

    :p

    Were these people larger than life to us because they were way more visible above the routine of life in the 60's and 70's? So much more noise and distractions in life these days, seems to me.

    Good advise as to shear acoustic power. I wouldn't put the L150 behind any CW, though, except as to sensitivity and a proud-to-be-loud attitude.
