The iCS65B is an extremely cost-effective ceiling-mounted speaker with a fixed resistance designed for various occasions, such as background music and public broadcasting. This speaker uses a 6.5-inch professional-grade ceiling-mounted installation with a two-frequency full-frequency design. The low-frequency uses a 6.5-inch diameter moisture-resistant composite diaphragm, and the high-frequency uses a 1" aluminum-magnesium/silk edge diaphragm with adjustable angle, warm and thick overall sound, full mid-range, and delicate high-frequency. The grille adopts a frameless and adsorptive design, which is easy to install and disassemble. This speaker has a high cost-performance ratio, excellent sound quality, and a simple appearance without losing a high-end feel, making it a rare and good choice. It is very suitable for use in many public places such as shopping malls, restaurants, and cafes.
