The Line 212-SP is powered by two power amplifier blocks in Class-D technology with a total output power of 2kW. The 'Click & Fly' system, it's simple to mount and cluster. Thanks to some internal re-design, the active version of the Line 212 is not significantly heavier than the passive system.
The SW 215E features a multitude of stacking grooves, which when combined with one or more Line 212 cabinets, allow for simple and precise alignment and help to stabilize the entire stack. Its use of modern chassis, tunnel, and enclosure technology gives it more punch in full power operations than comparable systems, say the company. Because of the phase compatibility, this subwoofer can also be combined with all other K&F systems.
