Kurzweil KS40A 4” Active Studio Monitors

Compact, Self-Powered Monitors

Our motto, “It’s The Sound” applies to not only keyboards, but to every step in the process of making music…. And so Kurzweil is pleased to present a new line of affordable, compact self-powered monitor speakers. The first model to be introduced, the KS-40A system, is a solid value, competing favorably with other monitors in and above its price range.

We believe the most accurate sound comes from the right combination of ingredients. Housed in a heavy, thick-walled, non-resonant wood cabinet, the KS-40A’s sport a magnetically shielded, two-way, bass reflex design and a compact footprint.

Featuring a premium 3/4″ dome tweeter and wide-range 4″ woofer, 20Wrms system amplification and separate volume and bass adjustments, the KS-40A’s are an ideal monitoring solution for the personal project studio or keyboard setup.

High frequencies are crisp and clear, low frequencies are balanced and warm, imparting a transparent sound to the KS-40A’s with equal amounts of presence and clarity. For musicians who are on a budget but are unwilling to compromise when it comes to sound quality, the KS-40A’s are the perfect compliment to our other affordable, high quality product lines like the SP and PC3LE series.
