WL 18 SW

When a strong sub-bass foundation is desined, the high power Sub woofer WL18SW is the ideal supplement to the Full Range Systems

The extremely compact dimensions of the WL18SW are just as convincing as the enormous sub-bass and the attainable maximum sound pressure.

The WL18SW is designed for universal use at the highest level. The subwoofer reproduces a lower frequency of 30 Hz for use as low frequency range system in theaters or in cinema as well as the precise contoured bass punch at live and club events.

The WL18SW is equipped with a newly developed 18" chassis which can bear peaks of up to 2kW, and because of its high linear deflection, it is capable of moving large volumes of air. The frictional losses and distortions which normally occur because of the high air velocity have been substantially reduced because of a new tunnel and enclosure design. Compared to conventional constructions, the exponential tunnel geometry of the WL18SW plays a crucial role in the outstanding performance and the compact dimensions.

Optionally, the WL18SW can be delivered with a selectable low-pass filter which facilitates, as desired, simple parallel operations with the Full Range Systems or the operation with an external active electronic system, i.e. with the digital system controller.

The WL18SW is an impressive bass system which combines excellent reproduction in the low-frequency-range with excellent sound pressure in compact form and is recommendable for a wide variety of professional uses.
