Which of the larger Pro Monitors had this feature?

That did not require the need of bi-wiring-amping?

I know the 4430/4435 were two. Were there others similar? "ala rotary switch, or?"

I’m going to interpret your question as “Which large, pro monitors can be single-amped?” I am going to define “Larger pro monitors” as those designed for far-field monitoring, and playback at realistic levels. Here’s a list, probably not 100% complete, in reverse chronological order, of JBL’s large studio monitors. If you are looking for a single-amp, larger monitor style speaker, you would also need to consider all the generations of large-monitor type speakers that JBL made for the Asian home market, and the current large monitor style speakers sold through JBL Synthesis dealers.
M2 - current, bi-amp only with external crossover, or filters built into amplifiers.
4344Mkii - bi-amp or single-amp, via removable straps on terminals.
DMS-1 - bi-amp only with external crossover.
4435 - bi-amp w/external crossover or single-amp via rotary switch
4430 - bi-amp w/external crossover or single-amp via rotary switch
4425 - single-amp only
4355 - bi-amp only with external crossover
4345 - bi-amp w/external crossover or single-amp via rotary switch
4343, 4343B - bi-amp w/external crossover or single-amp via rotary switch
4315 - single-amp only
4350,4350B - bi-amp only with external crossover
4331A, 4333A - bi-amp w/external crossover or single-amp via rotary switch
4333 - single-amp only
4332 - bi-amp w/external crossover only version of 4333
4331 - single-amp only
4330 - bi-amp w/external crossover only version of 4331
4320 - single-amp only

The UREI 813C/815C large format monitors are single amplifier models.

Yeah, I thought about including UREI, but was not sure the JBL fans consider UREI JBL enough…

4340- bi-amp only with external crossover
4341- single-amp only

:) Understood, but the "C" version is all JBL. E-145/2425 on the coax and 2215 for the helper.

Thank you very much folks. This was the exact information I was looking for.
