For producers and sound engineers looking for deep sub-bass, here is the answer: Sub12Made in France in Focal’s own workshops, this subwoofer delivers un-rivalled articulation, impact and depth. Thanks to its 13” (33cm) speaker driver with ‘W’-shaped cone and very high excursion, as well as its BASH amplifier with 600W RMS and 1000W peak-to-peak power, the sound reproduction is more impactful and faithful than ever.
In addition, there are optimised braces and a front vent inspired by Focal’s Trio11 monitors, as well as internal and external vents to reduce noise and distortion. At the back, a full set of bass controls can be used to perfectly adjust the settings for any system – low-pass, high-pass and variable phases – making Sub12 a truly remarkable professional tool.
