i was so sure speaker phasing had been done right that i did not check again with an Ohm meter.

i reversed the wires going to the left rear speaker and now all's nice;
rear speakers facing each other and no screechy noises in my ear.

thanks a lot Sir Quack for your tip.

i double checked the time delay, and it's ok, Mark.

:-D
