Thanks for posting it guys, and sorry for my late response.
The FRP looks very impressive, Dr. D!
Thanks Eric for posting it. I am a bit worried about that 150 hz peak with the BIB , which did not seem to occur in my room ,with the pAWO (maybe the room or the PAWO). But the PAWO does not go below 40-45 hz, i don't think.
So the BIB will subjectively probably have better bass. Hmm, not sure if I should build a BIB now for these. Wonder what BIB does for polar response, and mid range frequencies, versus the PAWO. Easiest way is to build one and find out I guess. I really like the PAWO design because it seems to be like a little horn, but does not mess up the mid bass a lot.
Any one have thoughts : especially folks who have compared BIB to other configurations like BRs?
