The iCS65 Fixed impedance bevel face In-Ceiling Speaker is a professional-grade speaker product. Its angled ceiling embedded installation design uses a slope angle of 25 degrees, which changes the sound reflection trajectory and makes the sound more three-dimensional. The low frequency uses a 6.5-inch diameter moisture-proof composite diaphragm, and the high frequency uses a 1" aluminum-magnesium/silk edge diaphragm with adjustable angles, which makes the overall sound warm and thick, the mid-range full, and the treble delicate. At the same time, its grille adopts a borderless and adsorption design, which is very easy to install and disassemble. The iCS65 Fixed impedance bevel face In-Ceiling Speaker is suitable for various occasions, such as high-end background music, custom home theater, cruise ship audio system, etc. Its high-quality sound and convenience of use make it an ideal choice for audio enthusiasts and audio industry professionals, and it can be said to be a very outstanding speaker product.
