FAQ

Q1 What size venue is this sound system suitable for?

A: Our performance sound system features a modular design, allowing for flexible configuration based on the venue:

Under 500m² (e.g., bars/small theaters): We recommend 2 main speakers + 2 subwoofers + a 1000W amplifier.

500–1500m² (e.g., music festival secondary stages/gymnasiums): We recommend 4 main speakers + 4 subwoofers + a multi-channel amplifier array.

>1500m² Large outdoor performances: Linear array configurations are supported; however, a customized configuration based on the acoustic environment is required from an engineer.

Q2 How do you handle weather changes when performing outdoors?

A: Our professional performance series all feature:

IPX5 waterproof and splashproof design, with a cabinet made of moisture-resistant composite wood and a weather-resistant coating.

All-weather dust and sandproof mesh cover to protect the high-frequency drivers.

Optional waterproof flight case (sold separately) for touring in extreme weather conditions.

Q3 Is the speaker power sufficient to cover the rear seats?

A: Our system is optimized through both sound pressure level (SPL) and projection angle:

Peak SPL reaches 144dB, ensuring clear hearing for rear passengers.

The adjustable horn design (70° x 110°) achieves directional sound field coverage, reducing energy dissipation.
