kurzweil KS-40A monitor review

As the Great emcfraktal says: “Lets get right to it”

KS-40A monitors

So I bought a pair of Kurzeil KS-40A active studio monitors, and a lot of you guys are curious about this new to the market monitor, well the sound performance is really good. The sound is highly accurate, clear, crisp, with a beautiful flat sound response, and not a hint of distortion.

The bass that is produced from the small cabinet is somewhat surprising, but not earth-shaking or astonishing in any way, as the woofer cone is reasonably small (4″) however if space is an issue in a room/studio of roughly 3×3 square meters, it’s ideal and there is plenty of power to go around, (20 watts to be exact). Now, if you are looking for a set of “speakers” for your bedroom or living room, I wouldn’t suggest the KS-40A’s as they are not very loud, and more suited for studio application.

There are two sets of RCA inputs located on the rear of the amplified cabinet, Input A and Input B.

Input B is the one you will be using when producing your beats and tracks as the response is flat, if you are listening to mp3’s or movies/dvd’s you will use input A which has a bass control knob to adjust the bass level for convenience. There is also a built in mixer which allows you to play both input sources at once, why would you ever want this you may ask? well, If you are producing beats through line-in A you can use line-in B for a keyboard, guitar or any input source, but in my opinion this feature is pretty useless for anyone who owns a decent audio interface.

The KS-40A‘s are solidly constructed, ridged and sturdy, with a gritty frosted black vinyl finish, and feature rear firing bass reflex ports to increase bass response.

Overall the kurzweil KS-40A monitors can’t compete with the higher end and more expensive KRK, Alesis or beringer monitor sets, but if your a student or producer on a tight budget, you can’t go wrong for R999.
