All drivers are passive. If you do not use a passive crossover, you have an active speaker system, whether or not the amps are on board and whether or not the amps were furnished by the speaker manufacturer.
As an example, I would say that all single driver systems are active since they have nothing inserted between the driver and the amp, sometimes not even binding posts.
