ESS Satellite quad speakers

[Asburya]

Bought this set in 1978 they were listed as infinity wattage and I still have them but had to replace the cube speakers with Bose and the bass cube still has the 12” cube. I wonder if I could find any original parts? They have solid walnut cabinets and cost a small fortune back in the day. I pushed them through a Sansui quad receiver now I have 2 macs

Are you referring to the speakers that featured the Heil air motion transformer ?
