Frequently asked questions
Can either speaker work for both music and announcements?
The ceiling speaker is optimized for music and ambient audio with extended low and high frequency response, while the paging horn is optimized for speech with a 380 Hz–6 kHz band and built-in high-pass filter. The paging horn can handle announcements clearly but will sound thin for music; the ceiling speaker can play announcements but won't achieve the paging horn's output or feedback resistance.
Which is better for outdoor use?
The paging horn is designed for outdoor environments with its IP-65 weatherproof rating, stainless steel bracket, phenolic diaphragm, and salt spray corrosion testing. The ceiling speaker is designed for indoor flush-mount installation and is not rated for outdoor exposure.
What's the key difference in output and coverage?
The paging horn delivers 123 dB continuous output (peaking at 129–133 dB) with a focused 50° × 70° pattern for long-distance speech projection. The C24CT-BK provides 130° spread coverage for even ambient distribution in smaller indoor spaces without specifying peak SPL.
Which requires less installation complexity?
The C24CT-BK is simpler for drop-ceiling installations—it includes a back can and tile rails for standard ceiling cavities. The paging horn requires bracket mounting and outdoor environmental planning but offers greater installation flexibility for poles, walls, or exposed locations.
