Soundtube CM400I-WH 4 Inch Coaxial In-ceiling Speaker

Product Description

The SOUNDTUBE CM400I-WH is a 4-inch coaxial in-ceiling speaker finished in white. Coaxial driver design places the tweeter concentrically within the woofer, delivering full-range audio from a single enclosure. The speaker mounts flush into standard ceiling cutouts and disappears into the ceiling plane once installed. It suits distributed audio systems in residential and light commercial environments where a low-profile, unobtrusive speaker is required. AV integrators and low-voltage contractors are the primary installers for this type of unit.

The CM400I-WH fits typical in-ceiling speaker applications including background music zones, paging systems, and multi-room audio distribution. The white finish blends with standard ceiling materials in offices, retail spaces, hotel rooms, and residential living areas. It is sold individually and is well suited for zone-by-zone builds where installers specify speakers one at a time based on room count.

Compatibility

Installation Notes

Installation is performed by licensed low-voltage contractors or AV integrators familiar with distributed audio systems. Power down the amplifier or receiver before making any speaker wire connections. A hole saw sized to the manufacturer cutout specification is required for drywall installations; drop-tile installations may require a tile bridge or trim ring. Follow local building codes for in-ceiling wiring, including plenum-rating requirements where applicable.
