Listen further into the bass
Focal specifies 32 Hz to 120 Hz at ±3 dB. That extends the frequency range available for checking bass content; it does not guarantee an even response in your room.

MODEL COMPARISON
How it compares
Sub One is the more compact alternative to SUB12. Its 310 mm width can help around a workstation, but the 520 mm depth and moving side drivers also need space.
DESIGN
What makes Sub One distinctive?
Integration controls included
Level, phase, polarity, high-pass and low-pass controls help match the main monitors. A bypass connection supports comparison with and without the subwoofer.
SYSTEM SETUP
Connections and placement
Source and volume control
- Use the balanced line inputs and monitor outputs for a compatible stereo bass-management path, or the balanced XLR LFE input for an appropriate multichannel source. For a cinema processor, check its subwoofer output connector and signal level against the XLR LFE input; the appropriate connection depends on the processor. Set filters for the actual signal path.
Room and listening position
- Choose placement through listening and measurement. Level, crossover, phase and polarity need to work with the main monitors; adding a subwoofer does not itself correct room modes.
