Thanks for the additional information! And, floor bounce question

The Blauert tapering-off of localization between .68 and 5 milliseconds makes a lot of sense. That explains why a strong, distinct early reflection (like off a bookshelf edge along one sidewall) can pull the imaging off to the side. Most annoyingly, it can pull the high frequencies selectively, so that the sibilants come from a different direction than the rest of the singer's voice!

Very interesting that the ear hears more coloration from vertical than horizontal reflections! I recall a paper by James Kates (something about "A perceptual criterion for loudspeaker evaluation") in which he studied the subjective coloration imparted by a single reflection delayed by various time intervals. I think he found that at 2 milliseconds delay the subjective coloration peaked. This is right smack in the middle of floor-bounce territory.

Now I've read arguments that the floor bounce is benign because we're so used to hearing it that we ignore it. Do you have any comment on the relative audibility of the floor bounce reflection? I seem to recall a throw rug in your home theater room, but the memory is fuzzy. Or do you use the coffee table to break up the floor bounce as it climbs upwards towards the couch?

Thanks,

Duke
