Tweeter panels. They made "hybrid" speakers with acoustic suspension woofers and a group of four of the tweeter modules angled so they'd be tangent to a sphere above the woofer, all in a conventional cabinet.

Yep. But they looked different and had features (insulated wire stators) that helped prevent arcing.
I'm trying to find some good closeups of the Janszen module. As I recall, it was 6 inches square, black, made of a thermoset plastic like Bakelite, and unique-looking because of the wire stator design.
