Quested SB10R

A Reference Partner to Complement the S Series

Designed as the "companion" subwoofer for the S series, the SB10R extends monitoring capabilities where standalone speakers reach their limits. Its size and 10-inch transducer are engineered to deliver bass that is both dense and clear, without masking the low-mid frequencies. The approach with remote amplification and control via the SBC250 sets it apart from a classic subwoofer: all integration is managed from the rack unit, simplifying installation and recall of settings.

Who It's For and What It's For: From Mixing to Sound Design

The SB10R is aimed at studios and home studios that want to hear (not just "feel") the extreme low end: electronic music, hip-hop, modern pop, post-production, video games, sound design... It allows verification of the kick, sub-bass, room resonances, and bass management across different listening systems. The bypass function helps instantly compare a mix with or without sub, useful for maintaining a coherent low-frequency spectrum.

Integration Settings: Filter, Phase, Polarity, Gain

The heart of the system is the amplified SBC250 controller: it provides essential tools to align the subwoofer with your monitors. The variable filter from 40 Hz to 135 Hz allows selection of a clean crossover frequency depending on speaker size. The gain control from -14 dB to +6 dB facilitates balancing the sub level, while the phase adjustment up to 160 degrees and the polarity switch plus/minus optimize acoustic summation at the listening position.

Adjustable Bass According to the Room

The frequency response can be adjusted via the controller (down to 20 Hz), helping to tailor the subwoofer's extension to room constraints and working style. The result: a more reliable low end, with a solid foundation without excessive trailing.
