Critic Reviews

KRK S10.4 subwoofer review | MusicRadar

A hefty subwoofer that delivers exceptional performance, the KRK S10.4 impresses with its balanced input options and good bass extension. However, its considerable size may pose a challenge for smaller setups, and the absence of a dedicated LFE input could be a drawback for some users.

KRK S10.4

The KRK S10.4 delivers a robust low-end performance with its powerful 160W Class-D amp and flexible crossover options, making it a solid addition to any studio setup. Its clean sound enhances stereo imaging, while the build quality is commendable. However, the lack of grille protection means careful placement is essential to avoid damage. The absence of a built-in room correction limits its adaptability in smaller or acoustically challenging spaces. Overall, while it excels in sound quality and power, potential buyers should consider their studio environment carefully before committing.

The KRK S10.4 subwoofer delivers solid low-end performance and seamless integration with various monitors, making it a strong contender for those seeking enhanced bass response. Its durable build and user-friendly controls are commendable. However, the lack of an updated manual and a footswitch can be frustrating for users, and the volume control could be better designed.
