Key Features

Feature Benefit
Deep, Controlled Bass A low-tuned bass-reflex enclosure delivers strong low-end impact. Airflow-optimized elliptical ports reduce turbulence and port noise to help preserve definition at high output.
Clear Vocals and Instruments Horn-loaded lower midrange drivers improve efficiency and headroom, while additional midrange drivers above the high-frequency section support clarity over greater distances.
Consistent Audience Coverage BEM-optimized waveguides and phase plugs provide even, controlled dispersion across the listening area.
Reduced Rearward Sound The passive cardioid column directs sound toward the audience while attenuating midrange energy behind the system.
Integrated Signal Protection DynX® DSP manages signal processing, with advanced limiters helping maintain controlled performance during demanding passages.
Straightforward System Assembly Plug-in connections eliminate separate speaker cables between the subwoofer and column sections. Automatic column detection simplifies setup.
Durable Construction and Handling Protective enclosure finishes, four ergonomic subwoofer handles, and recessed column handles support regular professional use and transport.
