Acoustic Speakers of unknown origin

I've been looking at some speakers on FB marketplace for a while, but I haven't been able to figure out the brand, model, or if it's actually worth it to get them. I'm sure they'd be better than what I have now, but it'd be nice to know what I'm actually buying. The attached images are from the seller's listing.

I'd give them a pass unless they're really cheap (like under $20). Based on the vintage of the upper three drivers, I suspect the woofers aren't original. And it's odd that they'd use a piezo as a mid-tweeter, since typically they can reproduce higher frequencies than a cone (those CTS cone tweeters are decent, though). Most likely designed by a marketing team first, and an engineer second.

At any rate, these were probably a "house brand" from one of the many audio retail stores that existed in the 1970s.

Can anyone help identify vintage technic speakers?

Was gifted a set of speakers that my father had when he was younger. Would love to get working again, even if only for reminisce. Speaker boxes appear unbranded, labeled "Acoustics V Four way air suspension speaker system". 1 of the mids has a damaged cone. Only information I have found so far...

Vintage "Acoustics V " Speakers?

So, i acquired a pair of these speakers for free, and they need work, mainly subwoofers, but I'm sure the others will need work too. Before I go chasing anything down thoough, can anyone here tell me anything about these? I can't seem to find anything online. I would imagine they're from...

The very top tweeter look like the tweeters I had on an old set of RCA two way speakers. Though I am only assuming that they were the original speakers. I saw them in a barn at a friend of an old girlfriends, I asked if he was selling them, he told me that I could have them.

That was back in the mid 80's and they were old and faded then, but they worked and was the first set of speakers I had that I didn't put together myself. Back then my putting a set of speakers together was a full range with a tweeter and a cap and the cabinets were tailored more towards what wood I could find than the parameters of the driver's.

I didn't have much to compare them to but I had them for several years as my only speakers With my Marantz 2215b. That's an old Infinity car speaker top left in a cobbled cabinet

Yes, those CTS phenolic ring tweeters were extremely common on 1970s speakers.

The CTS phonelic ring tweeters are actually not bad (My shop Interaudio 1000 use them) but the rest of the speaker components are questionable.

I am pretty certain those are Criterion 4x speakers.

If you're talking about the ones in the OP, the only thing they have in common with the 4x is the fact that they're a 4-way design. Literally everything else is different.

You’re right. I just did a better comparison and while they are definitely similar, those aren’t Criterions.
 

Acoustics III speakers from MI... who knows them?

I'm getting ready to refoam the woofers on a pair of speakers for my buddy. As the label states, they are obviously Acoustics III. The drivers all appear to be CTS, there's a circuit breaker on the back, a 5uf cap on the mid and a 2.2uf cap on the tweet, some thick wooly sponge-like stuffing...

I think the above poster was spot on with these being a house brand. Either that, or white van specials. Having "acoustic" in the name and not being ARs makes me think white van.
