Nice! can you share some photos when you finish?

and can you share a video or audio with the sound of this speaker?

I always wanted to know how it sounds to feel if it worth to build one

No problem, not sure what the outside will look like as of yet but looking at birds eye maple from a local wood vendor in my area. Really it will come down to what my wife lets me get. I did some research on these and my wife's uncle built them in 1970. For 55yr old cabinets they still sound good, even with a simple cheap 8 inch woofer and a simple compression driver.

IIRC it's based on the RCA 64B (pg. 60).

There was an earlier A model that was more tarted-up and less umber-industrial. Mr. Dybvig's flavor did away with the choke in the top of the RCA monitors as well as the flare changes.

......and originally was multi listed 😉; regardless, the MM is a 'B' right?

Can't swear to B being 90-deg stepped like A (and having chokes like visible in top of gutshot in your link) vs. tapered MM--Jonathan's archive in wayback is dead-end, but that'd be my bet. RIP Steve Schell.

At least I think they were all straight from the get-go of that '36 paper and HFO's book. Probably too-OT now and this belongs in the 64B thread(s). If nothing else, we have provided more industrial design ideas for @rclcomputer (er his wife) 🙂
