so a a few months ago, i came across these speakers in goodwill, $20 for the pair. i had to have them, specifically because the woodworking was 'off', but the rest of the build was spectacular. no oem-level carpenter/speaker builder would use straight cuts on the corners. it generally seals worse, so 45 degree mitered cuts are the standard because it's easy/stronger and cheaper to glue/seal.
this is what i'm met with on the inside-- nice felt padding on the edges, a semi-flared port edge, and fiberglass on the interior walls to reduce box resonances. they're very nicely built besides the bolt to connect the capacitor. clearly a lot of time and care went into these.
my guess is 50-60's build date. there's no visible model numbers, and the builder never signed their work in any way i can see. i'm excited to have even gotten my hands on them at all, as most custom-built speakers just get trashed once the original builder is done with them.
they sound mediocre as-is, the highs shake my ears(needs about a 10db cut), the bass is like a hiding cat--you know it's there, but it takes a lot of adjustment to bring it out of hiding...
