Barry - thanks so much the great photo collection! I know most of those speakers, and I know that mischievous look in the last photo.
I never did get to hear the 18" coax together with the 21" woofers, but did get to use them both separately, the MCM 21s lived at my house for awhile. They were the perfect OB woofer.
John said he wanted me to have the P.Audio 18" coax and some crossover parts, but I gotta figure out if I can get them down here to Panama where I live. They would be a fine souvenir of John's genius.
You are so right when you say Quote:
All sorts of wild creations made of parts that shouldn't have worked together. But they did.
That was John Busch's design philosophy in a nutshell. John took great delight in doing that. He was both out of the ordinary and extraordinary.
