SoundTube CM42-EZS-II-BK 4" Coaxial In-Ceiling Speaker, 4", Black

Optimize background music, paging and security monitoring in venues with limited plenum depth using the SoundTube CM42-EZS-II-BK 4" Coaxial In-Ceiling Speaker. Designed as a professional pro speaker, this model combines a 4" treated-fiber woofer and 0.75" silk dome tweeter to deliver intelligible speech and full-range audio with 87.5 dB sensitivity—so announcements, alarms and paging carry clearly across retail, corporate, healthcare and surveillance environments. The proprietary shallow backcan installs with just a 3.5" depth, simplifying retrofits where ceiling voids are constrained. A six-position tap switch supports 25/70.7/100V systems plus a 16 ohm bypass for transformer-less amplifier savings, making it easy to design efficient multi-speaker systems. Built for long-term reliability, the speaker includes a painted steel grille, tile bridge, conduit clamp and is EN54-24 listed and UL-certified for voice alarm and security use. Choose the CM42-EZS-II-BK for discreet, code-compliant audio in paging, monitoring and surveillance installations—contact us to specify or order for your next project.
