JBL - Control HST
JBL SPEAKER CONTROL HST
FEATURES
Wide-coverage installation speaker with hemispherical soundfield technology
The Control HST uses JBL’s HST (Hemispherical Soundfield Technology™) to deliver extremely wide horizontal dispersion (up to ~180°) and reduced primary wall reflections, making it ideal for wide-area coverage with fewer units.
Professional-grade audio performance in indoor/outdoor environments
This model provides high-fidelity sound from 50 Hz to 20 kHz (-10 dB) and includes a 100 W IEC power rating in the 8 Ω mode plus built-in 60 W/70 V–100 V multi-tap transformer options.
Durable and flexible mounting design for installation
The cabinet uses fiberglass-reinforced ABS with a wall-facing woofer and dual splayed tweeters, offering both indoor and outdoor suitability. The design minimizes the effect of boundary reflections which commonly affect wall-mounted speakers.
