Eastern Acoustic Works KF300Z

A 3-way full range loudspeaker in a vented trapezoidal enclosure. 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 operation with a passive LF/MF crossover. The enclosure offers a variety of mounting/suspenion points 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 loudspeakers available. It is particularly suited for portable or installed applications, including band PA, club systems, corporate AV, and theatrical productions. The midrange section incorporates a 7-in Radial Phase Plug™ based on EAW’s patented 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 grille that matches other KF300z as well as companion KF600z Series products.
