If L100 century is the twin of 4311, does that mean JBL did this a lot with twin models for home and pro audio, where just cabinets differ?
Is 120ti twin with 4412a ?
Any other?

There are few actual twins.
At any given time, the same or equivalent driver sets may have been used with different performance objectives, adjusting the box volumes, tuning frequencies, driver alignments, and crossovers to configure and voice the products differently for specific markets.
It's not just about the "look." 120ti is not a twin of 4412A, no....

Was there ever a pro twin to the Olympus speakers?

Or are these "just DIY" Olympus?
Thanks
