Cogan Hall, please shed some light


Hi

I've recently become aware of this brand, but I've not been able to find much info around the web…

Specifically, what do the various EM, EMD, EMF prints mean???

I guess those only refer to interconnect cables, what about their speaker cables?
I mean, are there other models than the Alto and Full Range?

Thank you

I've been reading around that they're are very stiff and difficult to handle, BUT you're giving me some hope, a tennis ball is quite small ;)
It’s been a while, but I seem to remember that different models were determined by the number of conductors or tubes. Because of their construction they can’t be bent or curved more than the diameter of a tennis ball. I found them to be nearly impossible to work with, and abandoned them quickly.
Wow...I haven't heard anyone mention that brand of cables in many years! I can't answer your specific question, but I do recall their unusual speaker cable design though. It was a hollow copper tube suspended within a black hose by round spacers. that encircled the copper tube at regular intervals. It was very exotic at the time.
