Well done @jmathers, looks fantastic! I played with the heater resistors a bit, until I got voltages where I needed them. I think I used 0.33r, and 0.11r, or 0.22r for the second resistor, I can't recall exactly.
That is a rather efficient use of space!
I like the heatsinks on the front, clearly it's allowed them to keep the overall package smaller.
A toss up between an Aleph 30? That is high praise IMO.
Good luck with sale~
I heard this earlier, and all I can think about is how it dramatically reduces that chance that I'll get to drive a Maloo too fast, mostly sideways, while listening to Rose Tatoo's 'nice boys' cranked up...
Bummer about Holden for sure.
I'm clearing out a bunch of drivers I don't use, and likely won't anytime soon. I bought all of these new, and only some have ever been used. They are all in original packaging.
I'll happily make deals for purchasing a bulk of drivers of course.
Fostex FF85WK - $60/pair, plus shipping, 1 pair...
Well I've been prepping my multicell assembly line. I have to make some more shelves to store bits and pieces or I'll end up buried under a stack of horn parts....
Plus I'm thinking I'll build a pair of Western Electric TA-7331-A's before too long, for @Tsingtao_1903
I thought they were usually deployed with large 'butterfly' baffles...maybe I'm remembering wrong.
I think they're very beautiful, and clearly made by highly skilled craftspeople. They're different, bold, and I suspect they sound pretty damn good.
I bet they need a pretty decent sized room...
I would probably run the -ve off the umbilical to the termination point of the, I'm assuming, ground buss (red line in diagram). Then each negative (-) lead of the caps have an individual wire to the same point.
I think the louvers are to tune the rear chamber, less directing sound, and more controlling pressures in the rear chamber.
Am I reading the plans correctly, it looks like the fronts are to be covered with a silk panel?
From Chuck Azzolina's post:
"My suspicions were confirmed with a decent sound but with boomy and boxy congestion. After two alignment adjustments though we were pleasantly surprised. "
I'm curious what the "alignment adjustments" were.... I suspect some stuffing behind the driver, as that...
They are super fragile, I nuked a few just trying to solder the little devils... so I put them on a piece of vero-board with some 26 guage leads... a bit of a heavy handed solution, but it kept my gorilla paws from nuking more of them ..:)
