SoundTube CM31-EZ

If you need reliable sound reinforcement for background music and announcements, SoundTube's CM31-EZ in-ceiling speaker will do the job without breaking the bank. Each features a 3" full-range polypropylene driver with butyl rubber surround, and they're weather-resistant, so you can use them indoors and out. A built-in transformer tap lets you use one amplifier to drive several speakers in an efficient distributed audio system. Fixed-wing mounting arms make installation easier, and the speaker's shallow steel back enclosure makes it a good fit for more in-ceiling locations. After we gather your information, we’ll send you a detailed system plan. It will include a link to a pre-filled shopping cart. Ordering is easy, and delivery is fast.
