The WSK-640CS 6.5" 2-Way Wall Mount Speaker is a high-quality commercial speaker designed for public address (PA) and background music systems. Its two-way speaker design, consisting of a 6.5-inch woofer and a 1-inch silk tweeter, produces balanced sound with clear highs and solid mid-range output, making it suitable for voice announcements and background music.

This speaker supports 100V / 70V line input as well as 8-ohm impedance, allowing flexible integration into professional PA systems. The multiple power taps (40W / 20W / 10W / 5W) allow installers to adjust the speaker power based on the area size and sound coverage requirements.

The enclosure is built from durable ABS material with a metal grille, ensuring long-term reliability while maintaining a modern and professional appearance. A stainless steel mounting bracket allows quick and secure wall installation, making it ideal for schools, offices, shopping malls, airports, and conference halls.

With a frequency response of 100Hz–20kHz and SPL around 90dB, the WSK-640CS delivers consistent and clear audio for announcements and background music in commercial environments.
