The NEXT-proaudio HFA115s is a professional active 15" bass reflex subwoofer engineered for high-level, extended low-frequency reproduction. Driven by an integrated 2-channel Class D amplifier module, it delivers dedicated low-end power while providing amplified output to run external full-range passive satellite speakers.

Equipped with onboard 24-bit/48kHz DSP, the subwoofer features eight selectable presets and real-time remote control capability using Soundware software via PC. Built-in automatic standby optimizes power efficiency, and a top-mounted 35 mm pole socket allows for streamlined ground-stacked speaker configurations.
