Bass management for the monitors
Left/right inputs and outputs, high-pass selection and adjustable low-pass filtering help divide bass duties between subwoofer and monitors.

Focal SUB12
Active studio subwoofer
A 13-inch W-cone subwoofer for a monitoring system that needs deeper low-frequency coverage and bass-management controls. SUB12 is a substantial 58 kg cabinet, so placement and integration deserve planning alongside the main monitors.

MODEL COMPARISON
How it compares
SUB12 is larger and heavier than Sub One, with a 28 Hz published low-frequency limit versus 32 Hz. Choose from the required listening level and measured integration needs, not room area alone.

What makes SUB12 distinctive?
Check the blend, then bypass
Level, phase and polarity controls support integration; footswitch bypass provides a comparison. Verify the combined response at the listening position.
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.
