The Kurzweil KS-40A Powered Monitors are a pair of active 20 watt combined output monitors designed for a project studio or keyboard setup. The cabinet construction is 100% wood and houses a 0.8" tweeter, a 4" bass driver, and a rear panel bass reflex port which allows sound from the rear of the bass driver to increase lower frequency output. The KS-40A also features a sub bass knob to boost bass output.

Two sets of stereo RCA inputs provide you with the choice of a flat frequency response with Line B, or a 9dB boost at 10kHz with Line A. The KS040A connects to the ¼" headphone output of any Kurzweil keyboard with the included ¼" to RCA adapter cable.
