12'' speakers?

[DennyMcFastLane]

Calling all Sunn aficionados!  Can anyone tell me what speaker Manufacturer, besides the well know JBL, were issued in the sunn cabs in the late 60's and early 70's ?  They looked like JBL's, because of the chrome cap, except they had a small felt hole in the center.  I think Sunn put these in the offset 4x12 bottoms?  Thanks.

There are numerous threads about the various drivers Sunn used over the years CTS, Eminence, JBL, Vega, and they even manufactured thier own during the Hartzell era.
