About SoundTube CM42-EZs-II

Make an impactful addition to your audio setup with the Soundtube CM42-EZs-II, a 4-inch coaxial, two-way in-ceiling speaker designed for those who appreciate high-quality sound and efficient performance. This durable and reliable speaker is engineered to deliver true high efficiency across its operating bandwidth, ensuring clear and powerful audio reproduction.

Crafted with a 4-inch treated fiber driver and a cloth surround, the CM42-EZs-II is housed in a sealed, drawn steel backcan, which contributes to its stylish appearance and enhances the speaker's maximum frequency response of 125 Hz to 22 kHz (-10 dB). This compact design does not compromise on sound quality, making it an ideal choice for a discreet yet powerful audio solution.

Installation is streamlined and secure, thanks to the included mounting hardware featuring a constant-tension winged mounting system. The 21-gauge "full metal" steel tile bridge ensures the speaker can be rapidly and securely installed in any sheetrock or drop-tile application. The color-coded (orange) tile bridge, optional pre-construction bracket, and a six-position tap switch accommodate 25-, 70.7-, and 100-volt applications with a transformer bypass position, simplifying the ordering and stocking process.

The CM42-EZs-II is perfect for environments where both aesthetics and audio performance are of paramount importance. Whether it's for paging or background music, this speaker is an excellent choice for hotels, retail stores, restaurants, airports, churches (under eave), medical facilities, or boardrooms. The entire CM-EZ-II series is tailored for installations that demand high-efficiency and rapid installation without sacrificing sound quality.

For those seeking enhanced bass response, pairing the CM42-EZs-II with SoundTube's CM1001dT subwoofer will extend the low-end frequency response down to 50Hz, creating a full-range audio experience that is both immersive and refined.

Choose the Soundtube CM42-EZs-II for a durable, high-quality, and efficient in-ceiling speaker solution that blends seamlessly into your space while delivering reliable, top-tier audio performance.
