hd Infra212

The hd Infra212 is a high-performance subwoofer with a hybrid cabinet design for reproducing frequencies down to 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 range, high efficiency, and passive directivity, the hd Infra212 can be seamlessly integrated into line array applications alongside the hd HLS20 and hd HLS24 HybridLineSource loudspeakers.

Cardioid dispersion behavior is generated passively with two or three stacked hd Infra212 up to 85 Hz or 65 Hz in front-firing mode. An M20 threaded insert on the top and side of the enclosure allows a distance rod to be attached. 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.
