Ugh, get those bad boys away from the wall and hooked up with some bi-wire cables!

I like the looks of those speakers."Sometimes you have to look to the past to understand where you are going in the future"Anger is just anger. It isn’t good. It isn’t bad. It just is. What you do with it is what matters.
You can use it to build or to destroy. You just have to make the choice. Jim Butcher

Interesting set of Bertagni speakers. 3 hundie!
https://detroit.craigslist.org/okl/ele/d/highland-very-rare-1975-geostatic/6970254239.html
They are interesting but they don't sound great IME/IMO (and FWIW, whilst I am slinging hip, happenin' web abbreviations...).
YMMV, of course.

but...
I believe that the drivers are foam -- unless I am confused (which is always possible) they're essentially an early implementation of the 'tactile transducers' or 'exicters'*; in this case, exciting a foam board.
I believe (!?!) the Bertagni transducers are a lot like the "polyplanar" drivers sold by LRE (e.g.,) in the early 1970s.
source: https://www.americanradiohistory.com/Archive-Catalogs/Consumer/Lafayette-1972.pdf
It was a thing in the early 1970s. It didn't quite catch on -- well, except that in recent years, it has sort of come back (with those aforementioned 'exciters').There is nothing new under the sun.

There were also, in the mid/late 1960s, a flurry of normal cone-type speaker drivers manufactured with styrofoam cones. EV was, fairly briefly, infatuated with foam cones. I haven't had enough ears-on experience with them to have a strong opinion, but it's safe to say that these didn't catch on either
This was one approach to strong, stiff, light materials to make 'truly' pistonic driver (mostly woofer) cones -- in the days before easy availability of today's fashionable paper alternatives for speaker cones (Kevlar, carbon fiber, various flavors of plastics, etc.).
I don't know if the foam cones have as horrific out-of-band frequency response anomalies (breakup modes) as today's wonder materials
1960s Electrovoice 12" foam cone woofer as used in their Regal 400 loudspeaker system. Note that hard plastic dustcap, too! Borrowed image.

Interesting history on foam Doc! Is there anything you don't know about speakers?
Hmmm, IMO foam seems to be, at least in my biz, not the right material if you're trying to control bending stiffness. Yeah you can re-formulate it, add fibers, etc, to stiffen it up, but seems to me there were better materials to start with.Basement: Polk SDA SRS 1.2tl's, Cary SLP-05 Pre with ultimate upgrade,McIntosh MCD301 CD/SACD player, Northstar Designs Excelsio DAC, Cambridge 851N streamer, McIntosh MC300 Amp, Silnote Morpheus Ref2, Series2 Digital Cables, Silnote Morpheus Ref2 Series2 XLR's, Furman 15PFi Power Conditioner, Pangea Power Cables, MIT Shotgun S3 IC's, MIT Shotgun S1 Bi-Wire speaker cables

I reckon that's true, and I further reckon why we don't see many foam coned drivers any more... and I even still further reckon why the Bertagni/Fisher speakers I've heard were... well... not so great.
EDIT: Oh, did anyone mention that Fisher sold some speakers using the Bertagni panels for a while? :P

hey -- someone else used PRs kinda sorta like that for a while in the late '70s/early 80s.

I think that's more like foamed polyurethane than Styrofoam (foamed polystyrene) though.

IIRC, these only accept NON-polar two-prong plugs
Back-in-the-day, I suppose these were helpful when audiophiles passed-out fell asleep on the couch during critical listening sessions.

He complained to Definitive and a new one was sent...now he has three of them. As it turns out, he had something connected wrong and the speaker is fine. So he is selling the new in-box one for $300!
