Ascendo, Meyer sound, alcons, pro audio technology. These are a few ultra High end brands for home theatre setups.
Ascendo and Meyer sound have 2 way speakers with built in bi amplification and obviously an active crossover.
Pro audio technology, alcons use external power amplifiers ( their own amplifiers) with active crossover applied in the external amplifiers.
So if it's a two way speaker then 2 set of cables would go to the speaker from the amplifier. ( This sounds like a passive setup but reality is its more of a active setup because of active crossovers. These Speakers are built with multiple inputs for each of the speaker driver, without a crossover inside them .
