where materials technology has changed drastically over the years. The only way Dayton-Wright was able to run a 12 kV bias was to seal the panels in SF2 gas. They also experienced various failures due to the relatively primitive coating technology of the 70s. Sound Labs, for example, runs their panels from 10 kV to 14 kV using modern polymer technology to make an ultra thin one micron diaphragm with a conductive coating that won't break down under those conditions. Their current panels are burned in at the factory at 800 watts. Try that with a pair of ESL 57s!While the magnetic drivers in your hybrid horns haven't changed much, some folks like Tom Danley have dealt with the coherence issues of using drivers with significantly different radiation patterns.
