Column speaker

The Column speaker offered by Ly International Electronics Co., Ltd. is a line‑array audio device available in four model numbers - C‑810, C‑820, C‑830 and C‑840 - each designed for different power needs. Rated power ranges from 10 W for the C‑810 to 40 W for the C‑840, while all models operate on a 100 V line voltage that simplifies wiring in large‑area sound systems. Sensitivity is listed at 89 ± 3 dB, providing clear output at modest amplification levels. These technical figures make the speakers suitable for both low‑ and medium‑power installations.

In commercial audio the enclosure is typically constructed from MDF or pressed metal to balance acoustic performance with durability, and the drivers are usually sealed‑box woofers that deliver reliable bass response. The industry standard impedance for such speakers is 8 Ω, and a frequency response of 70 Hz to 20 kHz is common, ensuring coverage of speech and music content. Ly International Electronics supplies the units with a clean aesthetic finish that can blend into modern interior décor, and the products comply with the applicable audio equipment standards.

The speakers are marketed for use in auditoriums, restaurants, retail outlets and home‑theatre environments, where even sound distribution is required.
