The hd Infra218 is a high-performance subwoofer Compact dimensions and exceptional power reserves combined with minimal distortion make the hd Infra218 a modern and flexible tool for touring and installation applications
The hd Infra218 is a high-performance subwoofer using hybrid enclosure design for reproducing extended low frequencies down to 32Hz. The compact dimensions, coupled with exceptional headroom and minimized
distortion makes the hd Infra218 a flexible tool for applications of large-scale tours and installations where high directivity control, extremely low-end and high SPL is required.
An optimally tuned, vented and hybrid horn loaded cabinet houses two linear, high-excursion 18-inch cone drivers. A large air-vent optimized port in the middle ensures a perfect coupling to the air while retaining minimum distortions. The Infras218´s 28 Hz to 100 Hz operating frequency range complements other Harmonic Design loudspeakers, allowing it to integrate smartly with LineArrays. Its cardioid directivity pattern works already with two or three stacked hd Infra218 down to 70 Hz respectively 55 Hz in front radiating mode.
Protective, plastic skids are included on the bottom of the cabinet that securely align with the cabinet‘s top slots. Units can be stacked normally or reversed for cardioid configurations. A separate Speakon connector is integrated in the front grill for easy setup of cardioid configurations.
