Vintage Superex Clear the big black circle is the speaker as far as I can tell up close

I love these! Very Art Deco-ish.

Backside of driver is covered by small pcb board so no point showing that.

Bump for a cool thread!
 
Philips SHP9000 Cineos the newer SHP1000 incarnation, nicer looking though. Same 50mm driver.
Loads of micropore tape directly on back and on a side port there, and of course the super-angled drivers. Foam there is part of another project.

The most important headphone driver in my opinion.
 Wharfedale Isodynamic or ID1. Genesis for orthos. Some design cues in this driver is still today state of the art.
What is striking is the simplicity in execution with maximum performance effect.

Sony DR-11 (somewhere around the 1970s I guess). Not sure I'd call them headphone drivers, but...
 
(The bottom bulge is roughly the size of a 5 euro cent coin in diameter.)

A product of the 70's, too! That's awesome.

Giant 53 mm dome driver of the Sony DR-Z5, 1978.

Hitachi HD-S5, from 1980, with "gathered diaphragm" (pleated). The very first aluminum driver? Nope. Beyer beat them by 43 years.
