Hello everybody and Merry Christmas
I have had this project in the works for about 6 months but really haven't had much to show so I waited until now to really post anything. I am both envious and intimidated with the amount of knowledge people on this forum have, most of you have forgotten more than I will ever know.
I have a set of almost new panels from a Martin Logan Quest including power supplies that I purchased from a user on the Martin Logan forums. I am going to build a hybrid ESL using the panels, custom stands and woofer enclosures.
I chose to use Fane Sovereign Pro 12" woofers for bass support. These have good response out past 500hz and have very low moving mass so integration with the panel will hopefully be pretty good.
I'm using the OEM Martin Logan power supplies with a pair of MULTICOMP PRO VTX-146-050-106 toroidal transformers wired together to get the correct winding ratio. Original transformers from Martin Logan are no longer available for this panel but other people have used these smaller toroidal transformer with good success.
The entire speaker will be ran off a Dayton 4X8 DSP unit, I will not be using any form of passive crossovers on the woofer or the panel. I will probably be crossing the ELS panel over with a 350HZ highpass @ 24BD/octave and the woofer will be bandpassed at 350hz and 60hz. The lower bass extension from 60hz and down will be handled by subwoofers. This seems to be a good starting point when looking at other hybrid electrostatic speakers.
The main construction of this speaker will be laser cut 3/16" steel, including the woofer enclosure. I am proficient in AutoCAD and routinely send large parts order out to a laser cutting company so for me this is actually an easy and cost effective option. I am not a good woodworker and my entire shop is setup for metalworking.
I plan on getting all the fabrication completed before the new year so more updates to come soon. I have included pictures of the progress so far below, I'm interested to here what everyone thinks.
