The only speaker I know of that comes close to a
Electrosat , is a pair of Eggleston Rosa's . They
have one of the best tweeters ever made , the four
6" drivers are ran almost full range. I have had apogee
and Magnepan speakers that operate in the same basic way.
However to me the Magnepans sound the best in this class.
The speakers I had were apogee stages, Magnepan 1.6R , I
believe Electrostats sound good for only a short period
of time , after that they start to cut up your ears...
After years of speakers the only one I can live with
are the Eggleston Rosa's , the only dynamic speakers I know of that have the same super transparency of the mention
speakers , and with more clean powerfull bass and peak output. They also are more room friendly and are best looking speakers I ever owned..
