Has anyone replaced the spring loaded binding posts on the Electromotion ESL model? I can't find a thread on that. The ones I found were replacing already nice banana binding posts.
I plan to create a new thread, adding some pictures and explaining why certain design decisions were taken. Mike Wright was a physicist and so he designed his speaker sort of like NASA would, not trying to be practical. This is probably the reason why financially the company never made any money. Anyway I read a few books on the subject, the Sanders book to name a few. From what I am seeing, there are certain design decision made by others that seem less than ideal.I will post the link here after i get started.
Hoping that the third set of bracket will arrive next week, but since going by post office and the July 4th weekend coming up,, I am not going to hold my breath.
I started the thread on it already. One thing to remember all the design criteria depends entirely on the use of SF6. The bias voltages were between 12 and 16kV. There was a reostat on the bias supply to lower the voltage on humid days and increase it on dry days. Even within the the mylar enclosed speaker, there was still enough ingress of humidity. The best thing it provided was preventing dust settling on the cells.I can well imagine. The space between the outer diaphragms would form a distributed acoustic resonator, particularly as the half wavelength approaches the spacing. Not insurmountable, just complicated. At low frequencies, though, the three diaphragms would move approximately in unison, and the wide spacing would allow for large excursions, ideal for a separate bass panel, if one wanted to go that route. If you create the thread I'd be interested in following it.
