Don't think would do search on the historian's thread but...

@Great, look at the archive here doing a search. Meanwhile, let's see what the subbers have to say. Welcome back!

Indubitably... lol !

Cool... should work nicely.

Welcome @Capitalcityguy Something's to unpack and not that familiar with Polk model. Owners of the CW-4s will chime in. What are you powering the speakers with? thanks... edit: Do you have a place to demo a pair?

Let us know. Maybe we can help.

If the price is right, along with pics, a demo is likely the only way to allay your concerns. You should be able to by looking and hearing then, to make a decision. Short of pulling the drivers or driver by the seller or yourself.

@wuzzzer

Cool... Not familiar with those or Atmos as @wuzzzer is apparently. Would take the lead from him.

Thing to look at for the date found in the link. Trademark dates 1980 is just the label... @susan

Welcome @Bsherck What are you powering with? Thanks!

Welcome @susan

Welcome back. Any chance we can get a pic or 2 of the 3 units. Should help with value. Thanks @Jon B

Thought saw a pdf posted somewhere recently on the subject of disassembly.? @MMurg stated earlier somewhere about the non availability of of parts. Agree with that. Thanks!

Well, welcome @MSinIL Had a Carver 500X driving some 1s, and as little as 45 watts vintage SS. Sounds good both ways. More bass control with more as, did so with KG-5.5 as well. Cool..

Not long now, we should be out of our mystery.

Architectural speakers?

Nice theatre @bobdog Not familiar with the model you are looking to use for Atmos. Thanks! edit: KPT, Premier?

Thanks for letting me know. Good job!

Beastly with decent reviews: . http://www.audioreview.com/product/amplification/receivers/pioneer/sx-838.html

Think good idea. Correct fuse and maybe simple buss fuses if any inside. Nice to have a couple of cheapo speakers to test deoxit working.

Nice!

Hello, would plug it in, turn it on, unless something wrong when you got it. Room temp, with nothing attached. SS not tube so yes, why not. Listen for power up relay and work the knobs, switches. If good so far and fuses checked, may could check it out, unless caked inside with dust. Just answering, not a bench tech.

Yes, I don't know. Therein may lay a mystery, yet, parts like diaphragms will continue to be needed, imo only. Remains to be seen. Thanks!

There is always hope. And hoping OP finds loose connection. For instance, If was me, would try another 8 ohm tweeter of any variety just to troubleshoot crossover, in the slight chance.
