There was a Purifi design called PTT SPK5. But as I recall, it took some anti-aircraft fire, and had to bail out.The new "demo" design (SPK16) has been on the website for some time... but AFAIK the missing ingredient, the Purifi tweeter, is STILL missing.
If anyone has a wad of cash burning a hole in their pocket, why not get in touch with Chris at Solen (solen@solen.ca), because Solen now has CNC cabinet making capability, and sketch out some ideas and talk numbers.
AFAIK the forks in that decision tree are:
1) Basic format (sealed, PR, ported, or OB), desired specifications, and budget.
2) Desired tweeter.
3) Desired midrange, if any.
You could take an existing semi-open-baffle design and have a sealed-back tweeter like the Beyma AMT and a Purifi dedicated midrange or two on an open baffle; with the bottom part of the baffle holding two Purifi 8-inch metal woofers...
Or you can do a "simple" 14 to 16 liter 2-way. Or, go big and see if you can pair the 8-inch Purifi alu-cone woofer with the right tweeter for a 2-way.
I fell in love with the Beyma AMT because it claims to have usable output down to 1kHz. My first guess at a crossover point was 1,800Hz, but Curt Campbell believed that a better handoff for the dispersion profiles would be 2,400Hz. But that's just going from A6 on a piano to D7 on a piano. Four notes.
Solen usually uses software to design quick crossovers, but they can do it the old-fashioned way from measurements and trial-and-error.
Perhaps if it all went well, Solen might give you a break on their otherwise prices if you in effect end up subsidizing R&D for a new product for them.
all my best,
