FOCAL SUB 12 – Studio subwoofer

The FOCAL SUB 12 is a professional active subwoofer designed to deliver precise, powerful, and distortion-free bass extension in studio monitor systems. It features a 13″ composite sandwich “W” cone woofer and a large laminar port for linear low-frequency reproduction (28 Hz – 400 Hz ±3 dB). Its internal 600 W RMS (1,000 W peak) Class D and Class AB amplifier delivers a maximum SPL of 124.5 dB at 1 m, ensuring headroom even in bass-heavy passages. Professional controls for low-pass and high-pass filters, phase, polarity, and level adjustments are available, as well as XLR Left/Right/LFE inputs/outputs and a 6.3 mm Focus/Bypass footswitch. Its automatic standby mode and robust MDF casing with veneered side panels and integrated handles complete a design designed for intensive use in recording, mixing and mastering studios.
