The Sound Town ZETHUS Series ZETHUS-115SPW is a 2400W powered line array subwoofer. It comes with one 15” woofer which offers solid and tight bass at earth shaking volume. The built-in amplifier operates at 600W RMS and has a peak power output of 1200W at 8-Ohm. Besides powering itself, with a Speakon output, the subwoofer can power additional full range line array speaker and delivers extra 600W RMS, 1200W peak power output. The Digital Signal Processing (DSP) function allows you to customize the sound curve based on application venues and the LCD display makes using the DSP a breeze.

The Sound Town ZETHUS-115SPW sub has multiple flying points and provides flexible mounting or suspension options. When combined with ZETHUS series PA speaker (ZETHUS-205, ZETHUS-205V2, ZETHUS-205WV2, ZETHUS-208, ZETHUS-208WV2, ZETHUS-110, ZETHUS-110W, available separately), the system provides superior sound that seasoned engineers and musicians demand at touring grade.
