K-Series

Overview

This two-way system allows for high quality, high fidelity playback at a considerably low price. With a frequency response that remains within +/- 3 dB, it meets industry standards for applications such as mixing and mastering. The vented enclosure allows extended bass response. With a passive 3rd order crossover at 1.8 kHz, the summation between the 6 1/2″ woofer and 1″ tweeter maintain a flat frequency response.
