I've learned things, imo very valuable things, from Toole and/or others' research that he renders accessible in his writings. Want to learn what matters most in speaker design? As you juggle the inevitable tradeoffs, want to know where you can compromise and get away with it? Do you have what might be a "better idea" and want to take into account relevant acoustic and psychoacoustic principles as you evolve your idea? Want to know where there might still be room for improvement in that magnificent butt-ugly horn monstrosity you mentioned?In situations like the horn monstrosity, you don't need Toole to validate what your ears tell you, but in most cases Toole will tell you WHY your ears reach the conclusions they do. When he doesn't, then the reasons probably lie in an area he has not delved into. For instance, on another forum, he told me that more research is needed in the area of thermal modulation - it is often much worse than we assume. He mentioned measuring a three-way system and finding that its midrange driver was compressing normal peaks by about 7 dB(!). Our horn monstrosity may not be perfect, but it probably doesn't have this problem.
Unfortunately I lack the energy to respond to your post point by point, and besides I would rather not get into an internet squabble with someone I respect.

Hi I didn't mean to suggest that everything he says is BS - not at all most of it isn't but let's say I agree with your point here "When he doesn't, then the reasons probably lie in an area he has not delved into. For instance, on another forum, he told me that more research is needed in the area of thermal modulation."
So... we disagree, but there's enough common ground that we can both stand on it? Done!
Thank you for such an agreeable disagreement!

Definitely good sir - now if only politicians could agreeably disagree on certain things and move on to stuff they agree on.
Yeah I know, but I keep trying to be an optimist and not crush the idealism too much.
Are you going to CAS in July (28-30)? If so let me know as I'll be covering part of it - I will miss the 28th as I'll be in Las Vegas.
I won't be at the Capital Audio Show, sorry. Nearly all of my energy has been going into prosound projects lately - some musical instrument speaker cabinets, and some studio speaker designs.
