Bohlender Grabner, Planer Magnetics, WWW.bgcorp.com. I have a 5.1 setup of their floorstanding series w/ 2 7.4 madrigal passive subs powered by 2 7.1 Citation amps and a monoblock. The front LR run in bridged mode @ ~500w. Outstanding for a home theater and audio comprimise, although I have a hard time finding the comprimise. Call them, good people to talk to.
DIY planar drivers
I would like to know if anyone knows if any DIY companies sell quasi-ribbon tweeter drivers, or are these drivers strictly a Magnepan proprietary design. I have sourced out DIY outlets for ribbon, planar-magnetic and electrostatic divers, and I would love to get my hands on a pair of these tweeter drivers. I personally prefer them for the midtweeter range and the ribbons for the 20kHz plus range. Any assistance would be greatly appreciated. Thanks, Steve Lewis
