Excerpt: An electrostatic panel would seem to be the perfect speaker. Its design neatly sidesteps the inherent weaknesses of conventional moving coil speakers. There's no cabinet or crossover, so phase anomalies, distortion and general limitations in quality that these things impart don't exist. Great so far, but there are solid reasons for electrostatics being so rare.
Pros: Hybrid design that integrates seamlessly, midrange and treble finesse, stereo image precision
Cons: Some may find it a little polite, fussy about positioning and system choice
