Alfatron ALFC-457 4.5-Inch 2-Way 40W In-Ceiling Loudspeaker
The ALFC-457 is a compact 4.5" 2-way in-ceiling loudspeaker designed to provide clear, balanced audio for distributed sound applications. Its 40W 8-ohm power handling and 20W, 10W, 5W, and 2.5W transformer taps support both low-impedance and 70V/100V systems, making it suitable for a wide range of commercial installation environments.
The built-in backbox provides a clean, integrated installation, while the magnetic grille allows for convenient access and a streamlined finished appearance. The aimable tweeter helps direct high-frequency sound toward the listening area for more controlled coverage and improved clarity.
With a 90 Hz to 20 kHz frequency response and 87 dB sensitivity at 1W/1m, the speaker delivers efficient, full-range performance from a discreet ceiling-mounted design. The white finish blends easily into typical ceiling environments, making it a practical choice for background music, paging, retail, hospitality, education, and other distributed audio applications.
