I read on your Weblog about your not getting good sound from the Frankenvandys and have a suggestion.
I've been building and using Wayne Parhams Pi designs for years, mainly his JBL 2226 with 1" compression drivers, 4 Pi Pros. Waynes just upgraded the crossover design and the performance of the 2226 takes a major step up
http://audioroundtable.com/PiSpeakers/messages/22762.html. So far I've tried it with my bigger 3.5 cu ft bass reflex box but I'm nearing completion on his 2.5 cu ft design. With the B&C DE-250 driver and Eminence H-290 horn, the combination is 97dB sensitive and is equally at home with rock, jazz or classical. Others have used various Altec and JBL horn drivers; a friend has 2" Altec 399s with Edgar Horns and that really is killer. Other mid-bass drivers can be used but the 2226 with it's shorting ring and massive motor combines taught bass with an excellent mid-range crossed at 1600 hz.
Wayne has the parts for sale but gives away the plans and all the 'secrets' at Audio Roundtable
