SoundTube CI15 3-Inch In-Wall Speaker

The CI15 is a compact, full-range in-wall speaker featuring a sealed back-can and a low-profile ABS/aluminum grille that remains virtually invisible in any décor. Its Speedwing™ mounting system ensures quick, secure installation, while the 3″ polypropylene woofer and bypass-capable 25/70.7/100 V transformer deliver clear audio in distributed or standard operation.

Equipped with a rotary tap selector offering 5 W @ 25 V or 20 W @ 70.7/100 V, the CI15 provides a frequency response of 115 Hz–22 kHz (±3 dB) and 45° coverage at 2 kHz for even sound dispersion. Its sealed steel enclosure minimizes back-wall interactions for precise reproduction.
