That interview of Mr. Dunlavy by John Atkinson is a must read for anyone interested in speaker design.His philosophy about building speakers ('do what you will, but start with optimal impulse response through time alignment and crossover topology and don't compromise in that department') is just so impressive. I like how we're reminded that flat amplitude response is fine, but only if it is the result of optimizing impulse response. The way he spoke of keeping a close eye on impulse response while affecting other attributes like frequency response and voicing - he makes it very clear what he believes to be vitally important.
Although one day it may be possible to have DSP algorithms that can overcome the limitations of passive crossovers, I believe this summary of Dunlavy's philosophy to be absolutely spot on. He's so candid and open about it too. The funny part is how EASY he makes his design philosophy sound, when in fact it's the most STRINGENT and challenging design philosophy out there. (Which is why so few speaker manufacturers bother with the effort!)
Rest in peace, Mr. Dunlavy.
Presto
