Magnepan

Tympani

MG-1 (the back was not normally exposed like this)

The brainchild of Jim Winey, panel speakers that are not electrostatic, but have many similarities.The company still flourishes today.

Famous for their three panel Tympani series in the '80s, the only ones I owned were the MG-1 Improved. Liked these a lot, but of course they needed a sub.

   Their SMG was a fantastic value for $500., and quite a few pairs of these still exist today.
