The hd Infra212 is a high-performance subwoofer with a hybrid enclosure design for the reproduction of extended low frequencies below 34 Hz. Compact dimensions and exceptional power reserves combined with minimal distortion make the hd Infra212 a modern yet flexible tool for large-scale touring and installation applications requiring extreme low- end, high SPL and great control over dispersion. The optimally tuned, vented, hybrid horn-loaded cabinet houses two special long-excursion 12” cone drivers with 4” voice coils.

A large, air flow-optimized center reflex port allows excellent air excitation with minimal turbulence and distortion. The transmission range from 34 Hz to 120 Hz makes the Infra212 the perfect bass extension for all Harmonic Design speakers. Thanks to its long throw, high efficiency and passive directivity pattern, the hd Infra212 can be optimally integrated into LineArray applications with HybridLineSource loudspeakers hd HLS20 and hd HLS24.

The cardioid radiation behavior is already generated passively with two or three stacked hd Infra212 up to 85 Hz, or 65 Hz in forward radiating operation An M20 threaded insert on the top and side of the enclosue allows a distance rod to be inserted. Protective skids made of high-strength PVC on two sides and corresponding recesses on the top of the cabinet ensure a secure footing. The NL4 Speakon jacks, mounted on the back of the recessed connector panel, are used to connect and route the input signal. A Speakon socket in the protective front grille allows cardioid configurations without special interchangeable cables.
