Frequently asked questions
Can the 447HC work outdoors or replace the GSB8-TN?
No. The 447HC is an indoor commercial ceiling speaker designed for suspended ceilings; it is not weatherproof. The GSB8-TN is specifically engineered for in-ground burial and outdoor use with IP66 rating.
What frequency ranges does each cover?
The Control 447HC covers 55 Hz to 20 kHz, making it a full-range speaker suitable for speech and music in commercial settings. The GSB8-TN covers 35 Hz and below, functioning only as a subwoofer extension that must pair with full-range speakers or satellite speakers elsewhere in the system.
Which has higher SPL output?
The Control 447HC reaches 119.5 dB peak SPL. The GSB8-TN reaches 114 dB peak SPL (108 dB continuous). The 447HC is louder overall, but the GSB8-TN is a bass-only subwoofer and not directly comparable—each serves a different role.
Are these compatible with 70V/100V systems?
Both support 70V and 100V operation. The 447HC includes dual-transformer design with multiple tap settings (60W, 30W, 15W, 7.5W) for precise level matching. The GSB8-TN offers 70V and 100V as power options alongside 6-ohm low-impedance.
