Yes, but for all that I've had fun in the past by slowly rotating
speakers while people listened with their eyes shut and they were never
sure if they could hear any difference, even when the speaker was
completely reversed!

That may demonstrate just how MUCH room effects matter, as compared to
direct sound. Though I'm a little surprised they didn't notice any
hf drop-off as the tweeters moved out of view.


Yes, the wall behind the speakers is only painted - doubles as a cinema
screen!

Lack of HF would, I'm sure, be put down to using LPs (if I did each and
every time) and the speakers that were used on different occasions were
my Ruark Paladins a long time ago and more recently the JM-Labs I got
from Rob.

Never tried it with the 'horns' - dont' know why, but I wouldn't expect
it to work...???
