Behringer Nekkst K10S Studio Subwoofer

85 out of 100. Incorporating 100+ ratings and reviews.

This budget friendly studio subwoofer was co-designed by KRK founder Keith R. Klawitter, which is an interesting collaboration to say the least.

The Behringer Nekkst K10S features a 10″ glass fiber woofer, driven by a 180 Watt amplifier, and as expected, it comes packed with as many practical features as Behringer can pack into its compact baffle, while keeping the price tag affordable.

Features also include XLR and RCA input/Output connectors, KRK designed cabinet with front port, and versatile controls that include variable lowpass filter and crossover frequency switch.

The overall sentiment was that this subwoofer is surprisingly good, especially when considering its price. Many have described the sound as being clear and well defined, especially when set at a moderate volume level. Others appreciate the added flexibility provided for by the crossover switching and low-pass filter.


Some users where underwhelmed with the overall volume, with some stating that it went below the level they expected from a 180W amplifier. There were also a few who reported out-of-the-box issues that required replacement.

Since January 2017, updated and new reviews and ratings have contained an increased proportion of negative sentiments.


Although we were recommending the Behringer Nekkst K10S from January 2017 onward, we took them off our recommended list in February 2018 due to the increase in negative sentiment I mentioned above which had driven its ratings down. You can see the higher rated alternatives, that we currently recommend, in our guide to The Best Studio Monitor Subwoofers.
