Speaker Identity, Help!!!

[Hopeou812]

Hi, I'm in need of identifying these speakers, the badge on them says Sound Research Inc., on the rear of the speakers it says Model 77, can anyone identify these precisely?? Thanks

they might be Sound Research Model 77 speakers but it is hard to tell from the pictures.

It says Sound Research on the badges themselves, they have cloth surrounds on the woofers...

Some people are saying they are AR but I don't see how, are these any good? What are the specs? I figure most any speaker with a cloth surround is pretty good! These are from the late 60's I'm assuming...

They are not Acoustic Research, so put your mind at ease. Anyone saying that is incorrect.

From appearances, they are generic late 1960s or early 1970s acoustic suspension speakers, with what appear to be generic drivers popular at the time. They have the look of CTS drivers, but that would be impossible to tell without pulling them and checking out any manufacturer marks on the back.

It would not be correct to say that 'any' driver with a cloth surround is 'pretty good', but that does not mean they are definitely bad. Again, it's difficult to say.

The terminals on the back have an RCA jack in the middle between the two screw-down posts. That would tend to indicate that they were intended for low to mid-fi consumer use, but again, that doesn't mean they sound bad, it just means they most likely were not aimed at a high-end market. Radio Shack and other consumer speaker makers used similar RCA jacks to connect speakers to receivers.

There was a speaker manufacturer by that name in Carson, California, but its trademarks have expired, so I presume it is out of business.

Without pulling the drivers and reading the manufacturer codes on the backs (if they have them), I suspect that's about all the information you're going to find. They were not, apparently, a national brand.

This is actually the first time I've ever seen RCA connectors on the back of a pair of vintage speakers before...

Thank you Wigwam, I'll pass on these then, they want $30 but, I'll just pass, stick with my Klipsch Heresy Heritage I's

RCA speaker connections were quite common on systems sold for "general family use" back in "them times". Made connecting the components together relatively simple.
The quality of components varied from manufacturer to manufacturer and model to model.
