The Pulz SUB218 extends the usable range of any loudspeaker to 35Hz. Its compact format offers an ideal companion to fixed or touring system. The SUB218 is equipped with two high power long excursion 18” subwoofer drivers.

SIC™ technology, increases bandwidth and efficiency while reducing total volume of vented bass loudspeaker by combining rear and front load in the same volume. Because rear and front load do not work in the same frequency region, it is possible, with a special calculation layout, to fuse both functions in only one. In practice, SIC™ technology, by using this new physical approach, virtually suppresses one of the two volumes and dramatically reduce the total size of vent loaded subwoofer.

When used with CX15 enclosure, the SUB218 is ideal for medium size Front of House. Multiple SUB218 can be operated for large Front of House.

With power handling capacity of 2000W (4000W peak) and response to 35Hz, the SUB218 is the answer for applications requiring additional low frequency extension at high SPL from a compact enclosure.

The SUB218 provides low end extension and upper mid bass articulation combined with very high power handling and efficiency.

Due to its SIC™ design, multiple SUB218 enclosures couple effectively while providing the bass definition and musicality that only a larger front loaded subwoofer can provide. The compact dimensions of the SUB218 provide a high degree of versatility for installations where space is at a premium. Typical applications include distributed subwoofer systems for club, open air systems or concert halls.
