About SoundTube CM500I

What sets the CM500i apart is its sophisticated engineering, which combines a 5.25" two-way speaker system with SoundTube's exclusive BroadBeam waveguide technology. This advanced tweeter system ensures a rich, dynamic audio experience with a broad operating bandwidth and exceptional off-axis performance, verified from 2 to 10 kHz. The speaker's adept low-end response reaches down to 55 Hz, making it a versatile choice for a variety of audio environments.

Crafted with a modern and sleek aesthetic, the CM500i features a low-profile grille that blends seamlessly into any ceiling, offering an elegant and stylish look that complements contemporary interior designs. The high-quality build is evident in every aspect of the speaker, from the proprietary motor-board to the precision-engineered components that ensure long-lasting performance.

Installation is streamlined and secure, thanks to the included mounting hardware and the constant-tension, fixed-wing mounting system, which allows for a fast and reliable setup. The speaker also includes a six-position tap switch with a transformer bypass position, providing flexibility and ease of use for different audio setups.

The CM500i is designed for in-ceiling background to mid-level Sound Pressure Level (SPL) applications, making it an ideal choice for delivering music and paging in a wide range of venues. Whether it's for courthouses, schools, retail stores, grocery stores, restaurants, hotels, casinos, museums, conference rooms, or churches, this speaker is engineered to provide clear and consistent audio.

For those seeking enhanced bass performance, pairing the CM500i with SoundTube's CM1001d-T 10" subwoofer will extend the low-end response to 41 Hz, creating a full-spectrum audio solution. The combination of discreet in-ceiling placement and superior sound quality makes the CM500i a premier choice for audio professionals and enthusiasts who demand the best in their sound systems.
