The Premium PR:O Series, a Proven Standard
Designed with the modular spirit of the Premium PR:O range, this subwoofer builds on more than ten years of success and over 150,000 speakers sold in Europe. It carries the series' DNA - wooden enclosure, carefully selected components, and advanced DSP - to provide a solid bass foundation for existing HK Audio systems while remaining compatible with legacy PR:O elements.
Who Is It For and What Are the Uses?
Ideal for contractors, DJs, bands, and versatile venues, the 210 Sub D2 fits anywhere space is limited but demanding tight and controlled bass. In bar-concerts, intimate clubs, community halls, or mobile stages, it effectively complements active satellites, even those without internal filtering, to form a coherent 2.1 system.
Key Features and On-Site Benefits
The built-in stereo preamplifier and Mid/High outputs simplify wiring a complete setup without an external processor. The variable crossover frequency from 75 to 150 Hz allows adapting the junction with the tops according to room configuration and musical style. The DSP protects the system via a subsonic filter and peak limiter, ensuring clean bass and consistent dynamic headroom. Finally, the low-resonance MDF chassis, steel grille with acoustic foam, and MultiGrip handles guarantee durability, transport comfort, and a professional look.
