Why Choose Focal SUB ONE Studio Subwoofer?
A studio subwoofer has to be accurate first and loud second. The Sub One’s Slatefiber drivers, 114 dB peak output and flexible filtering let a small studio hear the bottom octave properly, which is where mix decisions about bass and kick drums are actually made.
Key Features
Dual Slatefiber drivers: two 8-inch long-excursion Slatefiber drivers in an opposed layout cancel vibration.
200 W Class D power: two 100 W amplifiers for clean, controlled low-frequency output.
XLR satellite routing: balanced XLR inputs and outputs route the signal through the subwoofer to the monitors.
Flexible filtering: variable low-pass filter, 60/90 Hz high-pass for satellites and polarity control.
114 dB peak output: enough level for midfield studios as well as nearfield setups.
Best Suited For
Project and professional studios running Focal Shape, Alpha Evo or Trio monitors that need accurate bass extension to 32 Hz. That is the buyer the Focal SUB ONE Studio Subwoofer is built for.
Setup and Connection Guide
Connect the interface to the subwoofer’s XLR inputs and the monitors to its XLR outputs, set the high-pass to 60 or 90 Hz to suit the monitors, tune the low-pass and polarity for the flattest response at the mix position, and calibrate levels with the monitors. Once connected, the Focal SUB ONE Studio Subwoofer is ready for its first session.
Frequently Asked Questions
What monitors does the Focal SUB ONE Studio Subwoofer pair with?
It is designed for Focal’s professional monitors, including Shape, Alpha Evo and Trio models, but works with any monitors over balanced XLR.
How low does it go?
32 Hz at plus/minus 3 dB, with a 120 Hz upper limit for the low-pass filter.
Does it have a footswitch input?
No. The Sub One is controlled from its rear panel; the footswitch-controlled Focus mode belongs to the Trio11 Be monitor.
