In Phase USW12 Dual 600W Underseat Subwoofer

  • Space-saving dual 6" subwoofer enclosure with built-in amp
  • Wired bass and phase control
  • Die-cast aluminium chassis for powerful, distortion-free bass.

The In Phase USW12 offers powerful bass response in a compact, dual-driver enclosure built with die-cast aluminium construction for strength and sound integrity.

With two 6” aluminium cone sub-bass drivers operating in tandem, this unit produces a combined 600W of peak output, delivering tight, punchy bass across a wide frequency range.
Its ultra-slim profile allows for installation in various locations, including under seats and within boot cavities.

A full wiring kit is included for simplified setup, and high-level input compatibility ensures it works seamlessly with both aftermarket and factory head units.

The wired remote control enables users to easily adjust bass levels and phase settings, tailoring output to their preference.

Tested against major competitors including Focal, Pioneer, and Alpine, the USW12 provides exceptional sound at a compact scale.
