Invert ?

@clio09- I did a cursory search- the booklet-- which was around 99 pages, now sells for astronomical numbers as an out of print publication. There are other things, though- listening tests, which I believe were done after the booklet, are in the AES archive-- free to members, otherwise a 30+ dollar monograph. I think there were a few articles, perhaps interviews as well, in the legacy press. Pretty easy to find on an open web search.

After I posted initially, about why my current system sounds terrible in invert mode, I realized that I had wired the system to run the midrange horn directly from my Lamm SETs(no Xover either), then jumpered the tweeters and woofers out of phase to the mid horn. The additional sub woofers are also dialed in to adjust delay/phase.

So, the system coheres as set up, but invert-- not good sounding. 

Beyond the recording polarity ( which unless you make your own references ( hint ), polarity and achievement of absolute polarity is math for the active electrical components ( do the invert or not ) AND importantly but beyond frequently ignored, how do your speakers do on the impulse test ?
 

@clio09 has it correct, there are many sonic curse or, i prefer blessings… can you hear polarity, pitch, phase, time…. or ? 

The wood reference fascinating and this thread excellent….. audiogon at it’s best….

also… the Herron gear has an AC inversion switch…. plainly audible… just to add to the myrid possibilities of neurotic listening….
