ABS Passive Series Speakers and Monitors The ABS Series cabinets can be powered by the ABS Active speakers. This means that you can buy one active speaker and one passive speaker as a pair. Power an ABS10, ABS12 or ABS15 with one of the ABS10A, ABS12A or ABS15A. They double as floor monitors as well. This saves money and makes your system more portable.
