The HD series is a professional line array column speaker that currently includes four models: HD1, HD2, HD4, and HD9. This series is made of aluminum alloy profiles, with a unified appearance and material. The only difference between different models is the number of speaker units and the resulting height difference. The numbers in the model represent the number of speaker units, all using full frequency speaker units with a diameter of 4.5 inches. The height difference of different models affects the output sound pressure level and also affects the effective controlled low frequency lower limit of the line array. In principle, larger conference halls should use longer line array.
The HD series adopts classic line array technology and is often referred to as a sound column due to its external characteristics. They arrange multiple small driver units in a straight line, creating a highly directional sound radiation pattern.
The following are the advantages of using line array technology in the HD series:
1. Accurate directionality: Precisely project sound to the target area, reducing peripheral interference.
2. Uniform coverage: Provides a uniform sound distribution, effectively covering areas with consistent listening experience.
3. Remote transmission efficiency: Sound waves are efficiently transmitted, maintaining high quality and low distortion even at a distance.
4. Expansion flexibility: Each model can be flexibly combined and expanded according to needs, adapting to different venues.
5. Consistency and aesthetics: Unified aluminum alloy profile box, beautiful and durable, suitable for various environments.
6. Easy installation and maintenance: Design multiple installation accessories for easy installation and maintenance.
7. Optimize frequency response: Using high-quality full frequency speaker units, high sound quality, suitable for music and vocals.
8. Sound predictability: With excellent acoustic characteristics, it improves sound predictability and facilitates system design.
The HD series line array column speaker provides users with a professional, efficient, and aesthetically pleasing sound solution with its aluminum alloy profile, uniform appearance, and excellent performance.
