When a strong sub-bass foundation is desired, the high power Subwoofer DSW1800 is the ideal supplement to the Full Range Systems.

The extremely compact dimensions of the DSW1800 are just as convincing as the enormous sub-bass and the attainable maximum sound pressure.

The DSW1800 is designed for universal use at the highest level. The subwoofer reproduces a lower frequency of 25 Hz for use as Iow frequency range system in theaters or in the cinema as well as the precise contoured bass punch at live and club events.

The DSW1800 isequipped with a newly developed 21" chassis which can bear peaks of up to 7kW, 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 beensubstantially reduced because of a new tunnel and enclosure design. Compared to conventional constructions, the exponential tunnel geometry of the DSW1800 plays a crucial role in the outstanding performance and the compact dimensions.

Optionally, the DSW1800 can be delivered with a selectable Iow-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 DSW1800 is an impressive bass system which combines excellent reproduction in the Iow frequency range with excellent sound pressure in compact form and is recommendable for a wide variety of professional uses.
