Beta Sound model number

[powerman]

These were found at a barn sale. I cannot find a model number anywhere. Made by Beta Sound Inc. Dallas Texas. I have read the few threats around on this manufacture but not much info out there. The 12” woofers were replaced and unknown what was the original woofers. Any info will be much appreciated. TIA

They look like well made DIY speakers. With those drivers I assume they sound great.

Looks like it might've once an been an 050 (is it about 41" tall?).

I don't remember the Klipsch woofers off-hand, but my guess is K22 (like Heresies) or the K42 from the Heresy Industrial Ported (HIP) flavor. Delta12A these days would be a fine replacement. If you don't have the other (assuming Clements) midhorn, it all becomes full-on homebrew but there are better choices recently than when they were made. All depends on what you want to do with them.

The model is a 1001B as can be seen on the crossover board I missed before. Company seem to make 6 different models from 1977 - 1981. This info came from Audio, Stereo Review, and High Fidelity buyers guide mags. Appear to be the same components that Klipsch used in various speakers. The woofer used in this system had a 95db/1/w rating.
