EAW KF300z - Manual

A 3-way full range loudspeaker in a vented trapezoidal enclo-
sure. Includes a 12-in woofer, a horn-loaded 7-in midrange
cone with Radial Phase Plug
™ , and a 1.4-in exit compression
driver on a 90° x 45° constant directivity horn. The internal
crossover is user-switchable for either passive or bi-amp oper-
ation (with a passive LF/MF crossover). The enclosure has six
fly points, three each top and bottom, plus an integral pole
mount cup. Handles are located for the best balance when
carrying.
The KF300z is one of the smallest, full-range, 3-way loud-
speakers available. It is particularly suited for portable or
installed applications, including band PA, club systems, cor-
porate AV, and theatrical productions. The midrange section
incorporates a 7-in radial phase plug based on EAW’s patent-
ed 10-in Radial Phase Plug
™ used in other KF Series products.
This design produces a time-coherent midrange wavefront
that is critical to ensuring good vocal articulation. The
appearance of the KF300z is enchanced with a curved gille
that matches other KF300 as well as companion KF600 Series
products. Six year warranty.
