Arny,

I'm trying to remember what speakers you are likely to use here, and how
their radiation pattern is.

Pardon me for hijacking the thread, but this reminds me of something I've
been trying to find for a while. I have searched the 'net high and low for
loudspeaker polar plots. Nobody seems to publish them! Maybe because they're
all so terrible? :-) The only two I've found are 1) for a huge PA horn, and
2) an estimate for a "typical" speaker shown as a crude drawing in a text
book.

Do you know where I can get a few *actual measured* polar plots for typical
bookshelf style speakers?
