Hi,Mr. Hiraga said (and it's also in the promo-flyer) that he uses modified GreatPlainsAudio coaxial, although the one in the speakers that were playing music looked more like original Altec 604 (because of the multicell horn). So, I guess it's not M...

Romy    I have not herd so much doulble talk in a long time. Some of the best sounding drivers on the market in the last 60 years, were for sound reinforcement. I do believe, in a 2 way speaker system crossed over at 800hz with a good wood horn i wil...
