Hello,
I recently purchased some rare DLK ULMs (electrostats made by Janszen). I believe these were the same units used on the Z-II CF which I owned and sounded wonderful. I contacted Janszen to see if they had any information on the unit and unfortunately, they did not. He did tell me they should play down to around 800hz and have a 2nd order (single L/C) filter ahead of the signal step-up transformer that rolls off below 800 Hz. The capacitor is a 4.7uf but I am unsure of the inductor value.
I have wanted to use the Dayton RS225s for a while. I'm tempted to build two enclosures with two RS225s in each and the electrostats sitting on top, I really believe that has the potential to sound amazing.
•Would the RS225 or RS225P be better?
•For load, would getting (2) 8 ohm and wiring in parallel, along with the Janszen in parallel be the way to go? Or, (2) 4 ohm in series with the Janszen in parallel?
•I do not have much experience designing crossovers. I would think a simple 1st or 2nd order would work. My concern is all the variables...load resistance, desired Q, flattening the x-over hump where the two drivers meet, etc, all come into play and I am unsure how to start.
