What are these??

The build is certainly a good bit newer than the woofers.

Worst case, those Peter Jensen designed Magnavox woofers alone are worth more than twice the entry fee.
 
The plug with the soldered leads to the pins suggests these were assembled from what was available. The massive oil caps suggests there was fairly interesting stuff available.

Did you listen to them?
 
I will look over everything this weekend and plug them into something and see if it works or blows my amp or catches fire!:eek:
If these are 8 ohm I would use them in my two 65 Fender Deluxe Reverb amps..:naughty::idea:

Few AKers are going to know that White Rock (OP's location) is basically an old bedroom community for Los Alamos National Laboratory. God only knows what kind of high quality electronics came out of their surplus property department since 1945. If I knew as a summer intern in the early 80s what I know now about electronics, I would have vacuumed up more stuff. My folks have an outlet strip on their garage workbench that came out of there, but that's about it.

Yep, the town was/is full of very smart scientists and engineers. It used to have the highest Ph.D ratio of anywhere in the USA.

I would not be surprised to find some ridiculous components in a homebuilt speaker just because they were available for free or pennies.

OT - I've heard tales about the surplus stores there and that they were fantastic. Anywhere there was government tech research you'd find that. Another is former military bases especially USAF. A lot of 'tron stuff ended up in cellars & garages of employees and it still comes out during yard sale season,,,,. The closest I've been to a "good" US Gov. surplus store was Skyway in FL. Through the 90's in addition to aircraft surplus they were getting ex-NASA stuff. Absolutely amazing things there.
 
Those oil caps are fabulous! I bet they are spot on as long as they haven't leaked. At 500V there's no way they would be damaged in a speaker. They last virtually forever. Full of PCBs though so if you see anything leaking, be extremely careful.
 
Did some work with PCB containment for a few weeks full gear it sucked and it was hot.
We had a surplus junk store in LA the Black Hole, it was a candy store of anything one room full of cases of vacuum tubes bins full of caps, resistors, transistors of every shape and size. Some guy came in once a year and buy up a bunch of tubes.
I managed to buy a lot of all military grade GE 6L6 and mullard 12ax7 and a dozen or so Tung-sol 5881 tubes all in boxes.
Wish I would have not used them and sold a few when I was playing electric guitar back in the day.
 
Plugged them in today and listened to different styles of music.
Conclusion the guy had to be a classical music listener, these speakers sound smooth and not a lot of bass the top wizzer is a bit sharp so dropping the treble down made sense.
But than again I was running them through a Sony STR-AV480 Audio Video Control Center amp in the garage.
I could listen to Classical through these all day.
I am going to clean up the wiring on these as it is a mess and mount the guts to the inside of the top cabinet.
Then hook them up to my Rotel system but honestly I think these are good for classical and maybe acoustic orientated jazz.
One thing for sure they need power to sing.
