Custom made 80's speaker ID please

[Leland47]

Hi...perhaps some could give insight into what these speaker components might be?

Olsen cross overs...pots....seems to be a brand from the 50's? Can't seem to find any reference about those...

Custom speakers from the 80's? (per the ad) Is that boxy unit a ribbon tweeter or mid-range?

Heil Air Motion Transformers and CTS (likely) woofers.

I'd offer about half the asking once i verified the AMT's are good.

Olson was a mail order house like Lafayette and Radio Shack.
