I go into this on my website. I did a lot of window shopping on various
sites that sell raw drivers. I wanted something that was affordable,
uncommon in both name and design principle, and well made. When I got
it in my brain that I wanted a ribbon tweeter, I looked at all brands I
could find: Silver Flute, Hi-Vi, Fostex, Visaton, and
Bohlender-Graebner. The Silver Flutes seemed to have all the qualities
I wanted, and nobody else that I could find was using them. I got a guy
to build the cabinets for me, he did great work, and then I assembled
them. I actually wired the tweeters out of phase at first and thought
I'd shot myself in the wiener, because they just sounded off. I finally
figured out my mistake, and they sounded really good. Then they broke
in fully and sounded even better. The woofers were stiff as boards at
first, and the tweeter sounded edgy. After playing them for a long time
they finally came around, and although they weren't perfect they did
enough things really, really well that I knew I had something that
people would want to pay money for if they got a chance to hear them.


It sounds to me like the first prototype you produced is effectively
the final design. Is that correct?


Yes. The only thing I played with was the amount of insulation in the
cabinet. And wiring the tweeters in correct phase, of course.



How much tweaking was involved?



None, really. I know I'm supposed to play with crossover values and
port lengths and such, but the biggest flaws I found in the sonic
presentation were what I deemed to be limitations in the drivers
themselves. I think I got lucky, because as you know, I'm pretty
particular about sound. I'm kind of looking forward to dave's reaction.
Obviously he doesn't have any reasons to do me any favors, so I doubt
he'll fudge the truth.
