Manufacturing Capabilities

It really is a shame that there is no market for really good-sounding drivers.  Although I hope to have a useable one-off up and running before I die, it is the drizzling shits having to invent and build even my own templates and jigs in order to try to hold to acceptable tolerances while making formers, winding VCs, removing, modifying and re-fitting cones, etc., ad nuseum.  Suffering DIY, it happens all too often that a minor diviation from intended measurements or values renders the results no good, and most of the carefully-selected materials and sub-assemblies go to waste.  And all the time I am futzing around like a caveman, I am aware that all the machinery needed to streamline and properly control the processes is extent, and it's used every day to crank out one after another bad-sounding driver that will be stamped and shipped and received and re-labled and built into a bad-sounding speaker.

I have actually added a few tools to my already extensive collection because I "needed" them for some small part of the driver building process.  And some of these tools I've never even used yet.  Still, there are plenty more specialty tools I wish I had free access to.

Since I really do hate DIY, and since this has been such a giant drudge, you might reasonably think I'd find another way.

Well, I keep my ears open and my eyes peeled, believe me!

Selling Out
I suppose I have "learned a lot about drivers" and speakers over the years, but age has overtaken my production capabilities, and I am selling my stash of drivers. Included for sale is the Holy Grail of lower mid-range drivers, a particular variant of the 1939 Telefunken, 12", "full range", exponential cone, field coil. I also have 4 or 5 30" NOS exponential paper cones, along with gigantic old Electro Voice motors to drive them. I have 4 RFT 15" LF drivers, along with 12" wide range drivers with spectacular cones, also some rarely seen/heard American, German and Japanese drivers, all culled for sound. Most of these drivers are rare because they are among the best sounding available, so they rarely come up for sale., and in some cases very few of the best sounding variants of a given driver type were ever made, in the first place.

PM me if seriously interested, but please no merely curious inquiries.  Let me know what you're looking for.

PM inquire
How's that sell out going Paul? I wouldn't mind gluing together a proper sounding and nice 12" driver as long as there is a chance of successful integration of the rest of channels and the stack will work in a narrow room. Are all of them meant for OB application? I PM'ed you and admittedly it sounded more like a curious inquiry but I have an impression that the PM bounced back to me. Also all your posts regarding your system's architecture reveal pretty much nothing or I missed the crucial parts. Kind regards, W

Driver Sell-A-Thon
Hi, Wojtek
I get lots of PM from readers of this site; it should work.  Try again, and be careful with the spelling, etc.  Though I can  easily upload pictures to GSC Image Gallery, I can't seem to get them from the Gallery to the Board. Perhaps they are too big, and I just don't know how to make the files smaller?  Once we get an email connection I can send some photos.  I think I may have an old e-dress of yours?

Anyway, several of these drivers would not need fiddling with, if listened to below 100 dB in their proper pass band  As for my "System Architecture", it is "hair shirt": either phono OR CDs (no source switching), to "passive" TVC, to monster MA9-S2 amps, to speakers, with short cable runs.  Currently running rather large 3 - 4 ways that I built from Dick Olsher's plans, some years ago, although they are "tuned to taste".

As for "integration", I can offer ideas, but, after all, that's personal.  The "best sound" I ever had in my house was from one of my "stacks", mono, but I had to be 15' from the stack, in a 20' room which is not viable for me.  What all my drivers have in common is amazing, "curvelinear" cones made of paper that is no longer available, and several of these drivers are quite rare, either because few were made, or few have survived, or collectors grabbed them up.


Best regards,
Paul S
