I installed this late '60s 8ohm JBL D140R to replace the CTS. R for Rogers (organs) Also came as D140F (Fender)

It has the more rectangular Thiele ported cab (not my cab - found pic that shows port-shelf)

If you find the right one, they’re awesome. I plan on having another one day.
Yep. I’m not sure what it was with the ones I tried at several stores in SoCal during a week we were staying in Newport. One store in OC had five of them (because they’re close to the factory). They just didn’t feel right to me. Maybe the thinner neck profile will be better for me, although I’m pretty much neck agnostic and generally adapt.
