DallasJustice post this nice interview of Paul Hales of PHC speakers with Scott Wilkinson where he talks about speaker and room interactions. The views he expresses is that of "modern acoustics" which runs counter to what we traditionally thought we knew (and very much inline with the views of Dr. Toole, etc). While I have one or two areas of disagreement with him, as a whole, he is providing the right story and context.
Unfortunately the player they use for the video is special and you have to go to the site and watch it. And there is no speed controls so allocate the time to listen. It is worthwhile.
