As a former owner of KLH Nines and original Quads, I have a fondness for electrostatics. MartinLogan has taken the hybrid approach, using electrostatic mid/tweeters and powered dynamic woofers, and this has worked well for them. The latest feature of their approach is the use of DSP equalization, used in the Ethos. This is now being applied upmarket, and the speaker incorporating this approach, now in advanced prototype form (“two or three months from being ready for production”), on demo at CES was a speaker that is expected to sell for $9000$10,000/pair (right). The sign said Summit X Jr., but I was told that was just an interim name. The speakers certainly sounded most promising.
