DSPeaker Anti-Mode 8033S-II Subwoofer Room Correction Processor
The DSPeaker Anti-Mode 8033S-II is engineered to address common room acoustic challenges that plague low-frequency reproduction. This compact but powerful DSP unit utilizes automatic calibration through a supplied microphone to analyze room acoustics and apply up to 36 precise digital filters in the 16–250Hz range. It effectively suppresses standing waves and smooths bass response without requiring manual EQ tweaking.
Designed with flexibility in mind, the 8033S-II features dual line-level RCA inputs and both 0° and 180° RCA phase outputs, enabling easy integration with both mono and dual subwoofer configurations. It can even combine stereo and home theater signals via optional summing cables. The unit also offers selectable low-pass filters (60Hz to 140Hz) and two dipole correction modes (20–140Hz and 20–200Hz) to support open-baffle subwoofers - ensuring accurate compensation for natural roll-off characteristics.
Five EQ modes are available, including FLAT, Subsonic Filter Only, LIFT 15–25Hz, LIFT 25–35Hz, and a unique LIFT 20–30Hz mode exclusive to the S-II model, providing up to 8dB boost with built-in infrasonic filtering. The low power consumption (1.2W) and compact design make it suitable for always-on operation.
Whether for critical music listening or home cinema applications, the Anti-Mode 8033S-II offers substantial improvements in bass clarity, impact, and integration - especially when subwoofer placement is constrained.
