Why Choose the HL Large Line Array Series?

Professional sound reinforcement requires more than simply increasing speaker power. The HL Large Line Array Series is designed as a complete acoustic platform that balances output, coverage, scalability and installation efficiency.

High Output for Large Venues

With power ratings ranging from 600 W to 800 W and maximum SPL up to 133 dB, the HL Series is capable of delivering the sound pressure required for concerts, festivals, arenas and other high-capacity venues while maintaining clarity and dynamic performance.

Long-Throw Sound Projection

The controlled 100° × 7° dispersion and modular line array configuration enable sound to travel farther while maintaining more uniform sound pressure throughout the audience area.

Modular System Design

The HL Series supports scalable array configurations, allowing users to increase or reduce the number of cabinets according to venue size, audience capacity and coverage requirements.

Its modular architecture also simplifies transportation, storage and future expansion, making it suitable for both rental companies and permanent installations.
