Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about KRK 8s 8" Subwoofer.

Use cases and applications

  • An 8-inch subwoofer might not significantly enhance a setup with KRK Rokit 8s, especially in a 7x7 meter room; consider larger subs or different systems.

    Source

Setup and maintenance

  • Monitor speakers are not designed to sustain high volumes continuously; ensure audio quality to prevent long-term damage.

    Source
  • The KRK 8s Subwoofer's crossover should typically be set at the -3dB point of your monitors' frequency response, which is around 55 Hz for Rokit 5s.

    Source

Features and functionality

  • KRK monitors have a brick wall limiter, protecting them from damage due to excessive volume, but they still output about 110dB at max volume.

    Source
  • The KRK 8s Subwoofer does not allow simultaneous use of both balanced XLR and TRS inputs; it defaults to the TRS signal when both are connected.

    Source
  • Users can use unbalanced and balanced inputs simultaneously by utilizing XLR to RCA adapters, effectively bypassing the input limitation.

    Source
  • KRK S8 Sub is rated to extend down to 34.5 Hz, but this is seen as optimistic, with true sub-bass defined below 30 Hz.

    Source

User experience

  • Owners report needing to unplug TRS cables to switch to XLR inputs, indicating a design choice rather than a defect.

    Source
  • Owners suggest setting the crossover frequency between 60Hz to 80Hz for optimal blending with monitors, depending on room size and acoustic properties.

Critic Reviews

KRK Subwoofers - 8S,10S and 12S Reviewed - Bass in Place

musictech.com

While the KRK 8s Subwoofer offers decent low-end support for smaller studios, it struggles to deliver the visceral bass experience users might crave. Its design is sleek and feature-rich, boasting connections that enhance versatility. However, the lack of a sweepable crossover dial limits fine-tuning capabilities compared to older models. The 8s does well filling in sound for medium-sized spaces but falls short in translating the full weight of lower frequencies, making it less ideal for bass-heavy genres. For a modest investment, it’s a solid choice, but stepping up to the 10s may provide a more satisfying audio experience. Overall, the 8s is a capable but not groundbreaking option in the KRK lineup.
