**Wonderful full range field coils very hard to come by i have never seen another pair for sale in the UK. Hand made by Oleg Rulitt in Germany. Using vintage frames and coils with his own paper cones. They need 0-120 vdc to drive them i found 72-75 vdc worked well in my open baffles using a vari-ac transformer feeding 2 simple power supplys made up from bridge rectifiers and a capacitors. There is a fair bit about these on the web and a good review on glow in the dark.com. Only selling these because i want to move up the Oleg Rulitt field coil chain. One word of caution they have exposed electrical contacts on the rear so not for use with children around.**Looking for £800.00 +UK postage or can be collected from Chichester W.Sussex.

I don’t need any speaker drivers but I am curious about how they fix to the baffle?
These sound interesting but I need a (idiots) guide to what the following actually looks like…

Also I have vague memories that youve used with a tweerer and 15" bass unit- so guessing the single driver approach needs taking with a pinch of salt…How did you crossover?
Small clamps at the rear.

Most full range drivers need a bit of help on open baffles not the case when using front or rear loaded horn enclosure’s. Crossover’s are really simple 3uf cap on the tweeter nothing on the field coils and a inductor and cap on the bass. Can upload a pic of power supply when i get a bit more time.
