RE: Rear Panel of a ALTEC VALENCIA , stock or modded??

Posted by drlowmu on March 10, 2017 at 07:14:14:

Thanks mah,

Yep original owner modded box, neatly, painted it black. 802Ds will fit now !! Cool.

Its so STRIKING to me, looking at the photos from the URL you kindly referenced, seeing such a CRUMMY set of STOCK Altec crossover-to-drivers wiring, ( that MOST everyone puts up with, on such speakers ). Most ALTEC users never gave wiring, internal, much thought !!! NOT I. Not Joe Roberts. I routinely couple my amp-to-crossover and crossover-to-drivers MUCH MUCH better. Heck - 99% of the ALTEC users never heard what their wonderful ALTEC drivers can do !!! Sad to think about, but also hilarious.

To start, double-up (parallel) two 12 AWG runs to each 416 speaker polarity - Wonder soldered right to the terminal that holds the voice coil wire. This ALSO eliminates the less-than-ideal ( unsoldered ) stock ALTEC connector on the speaker's frame. Be sure to loop and tie wrap reinforce those heavy leads to the frame for mistaken tug. ( Double 12 AWG equals 9 AWG .) Mil Spec m22759/11 12 ONLY, need the silver, and maybe 16 AWG of the same stuff, single run, to the compression driver. Fulton lengths, of course - 57 1/8th inches if you don't know, from pre-1978 folks !!

Eliminate the 802D "press to fit" connector also, Wonder solder DEFTLY - QUICKLY, large iron, right to the aluminum diaphragm tabs, rags over diaphragm to avoid solder splatters !!!

Photo above is the positive woofer's terminal I will Wonder solder to, with rags over the cone to protect it when soldering ( only ).

Joe Roberts will cheer when / if we ditch the 811 horn!! Working on that, but a John Inlow paper walled Tractrix horn won't quite fit inside de box.

Ohh my goodness, I have gone off-topic,"hi-jacking" my own thread with my own personal agenda, whatever that might be. ( Better sound???? )
