OSD Audio ACE400 3-Inch Trimless In-Ceiling Speaker (Pair)
Description
The OSD Audio ACE400 is a compact, high-quality trimless in-ceiling speaker pair designed for discreet background music in residential and commercial environments. Part of OSD Audio's Architectural Ceiling Element (ACE) Series, the ACE400 features a micro-flange trimless design that virtually disappears into the ceiling, making it an excellent choice for modern interiors where aesthetics are as important as performance.
Despite its compact 3-inch driver, the ACE400 delivers clear vocals, balanced midrange, and crisp high frequencies, making it ideal for kitchens, hallways, bathrooms, offices, bedrooms, retail stores, and distributed whole-home audio systems. The polypropylene woofer with butyl rubber surround ensures long-lasting durability, while the paintable magnetic grille blends seamlessly with any décor.
Designed for quick retrofit installations, the speaker utilizes OSD Audio's dog-ear mounting system, eliminating the need for additional mounting brackets. Its shallow mounting depth also makes it suitable for installations where ceiling space is limited. Sold as a pair, the ACE400 offers an affordable and elegant architectural audio solution for background music applications.
