Ribbon midrange pros and cons

Please excuse the typos. ......

Thank you guys for all the responses. .those explanations were on the same lines as l was thinking ...l was particularly thinking of the infinity Beta ,the Epsilon and the new speakers PS Audio is working on...Paul says hes working on a 120 db. Ribbon midrange .l just dont see other manufacturers using these types of midranges and wondering why.l an going to Expona this weekend in Chicago to listen to some great systems. ..lm sure to be impressed. ...

Its funny that you mention the Apogee ribbons. ..back in the 80's my best friends father had a machine shop and he was making the framework for the Apogee ribbon speakers. He had two sets in his house driven by Krell amps and JBL 18 in.subs..That was our after school party system for many years. ....sorry to say his wifes cats destroyed them and about 20 years later he gave me both sets....they were so big it took two men just to move the tweeter column.They were easily the size of a front house door .l posted them on Audiogon many years ago and a guy drove from New York to Indiana in a rental truck to buy them...l had no interest in restoring them...Anyway the sound they produced was very open and airy with a big sound stage....and very detailed. ....but they lacked that dynamic punch you get from a traditional cone type speaker so l had no interest in them....
