You never know. The value of those whizzer drivers might lay in their ability to perform well in that particular cabinet, matched to that tweeter, using that crossover network. Without a refoam, its a mystery what their true potential really is.
Some of the fullranger guys here might recognize that driver. There were a lot of good whizzer cone speakers made that look like garbage on the face of it but in terms of sound quality do the midrange area very well. I'd make a separate speaker i.d. post aimed at the full range folks with the pictures you have here and see what they have to say. Somebody's got to recognize it.
Those speakers are 44 years old, Jensen wasn't a dirty word yet.

I was going to guess RTR tower speakers.

Tweeter could blow if over driven, not liquid cooled.
Impressive speakers, housemate had a pair in early 1980's, Tech HiFi, Stereo City?

The crossover pic from 2017 shows one of those old red and black ones that needs to go straight in the trash. Not sure what the big ones are, if they are NPE's they should be changed too. If film, maybe OK. I notice the OP said the tweeters were bright, but with no woofer surrounds and at least one crapped out cap, I would fix them before passing judgment.
Crossover and wiring looks a lot like many other small manufacturers in the 70s-80s. Shoot, the AR9's I had were full of wires all over the place.

Correct me if I'm wrong, but didn't RTR popularize the tall skinny tower speaker?
Late 1970's and early 1980's almost everything was different sizes of shoe boxes, Bose had a floor sitting cube though.
Who else had towers by 1981?
I suspect towers became marketable after panel speakers like Magnepan established that tall can be beautiful and that a serious audiophile had to be willing to surrender their home decor to it.

The AR9 was about 1981. About 5 ft. tall. Also the big EPI towers were around that time.
I think the ADS 1290s and 1590s came along in the very late 70s and were available for awhile.

ADS 1290 manufactured 1983-86, 1590-1986.
I got them confused with the 1230,1530, and the 2030, available at the turn of the 80s decade. The 1590 was also available in ‘83.

Looks like the start of a list.
Add to it.......
ESS AMT-1
Maybe some stuff from Infinity in the IRS series?
Tower speakers were the exception, not rule back then (late 1970's early 1980's).
By the late 1980's towers had taken over, no more odd shoe box proportioned speakers confused if they should be on the floor, on stands or in a really deep bookshelf.

The 600's have one front and two rear firing tweeters.

I cast my vote for home grown. They way the crossover is soldered together is a big clue. No manufacturer would float uninsulated connections like that. Also, speaker pairings are a little strange with Jensen wizzer cones and Peerless tweeters.
