So I finally dragged these out to check them out to get them ready to sell. One of them had something rattling around inside. I removed the woofer screws but I could not it out, it was stuck hard and not wanting to damage anything I removed the mid horn, which came out easily.
I found the mid horn s wires just dangling and one of the coils had come loose from the crossover board.
That was fixed pretty easily and a quick inspection I found that the box is well made with one brace between the front baffle and rear. There was no filler, which surprised me. These are pretty heavy.
I hooked them up in place of my soon to go Spatial’s with the EleKit Tu-8800 KT88 SET and took a listen.
Well guess what they sounded just like a Klipsch. I can certainly see the how and why there were so many companies started just to mod and repair Klipsch speakers. Yes the date on these speakers is 1987 and maybe they were special to some back then. The crossover has an electrolytic cap in the woofer section and 10 cent caps elsewhere. The Iron core inductors are ok except for the tweeter..
So I cleaned up the cabinets and gave them some elbow grease with some wax and Steve wool. They look good which is all I care about because hopefully they will move quickly.
Asking price on the web for similar shape examples range from a low $1k to $2500. I want to move them so I will try for less.

Despite their dismal sound quality I thought their quality control was more on point. You just said a lot about the Klipsch organization.

Yes those plastic horns are deadly. Could use a lot of dampening. I am wondering if that Flex paste you see advertised so much would work.
Its expensive $20 for a pint, but dries to a tough rubber consistency

I find it hard to believe Klipsch put this in crooked like that. Someone had to have had it out at some point....

This is a great project for someone who wants to take the time and effort to build decent crossovers, and possibly do something different with the horns if the price is right.

Forget that -- it's reactive. I recommend Q-Pads that are used to dampen automobile panels. They are a lead-impregnated self-adhesive pad that's easily cut with kitchen shears.

You can get them at;
Marty's Auto Paint in Rosedale, Maryland
Address: 7600 Pulaski Hwy, Baltimore, MD 21237
Hours: Closed ⋅ Opens 8AM Mon
Phone: (410) 866-6680

They are also effective to dampen the sheet metal of a amplifier, CD transport, or dac project.

Here is the manufacturer's WEBsite:

Thanks for the tip Walt. Found them on Amazon also.
