The IS4 C is an extended bandwidth, wide dispersion loudspeaker designed for ceiling or wall mounting in commercial/professional installations in airports, hotels, boardrooms, cruise ships, casinos, convention centers, restaurants, offices, houses of worship and retail stores.

The IS4 C incorporates a polypropylene diaphragm that provides distinct woofer, midrange and tweeter radiation areas to ensure superior-quality sound in foreground music, public address and paging applications. The IS4 C features wide dispersion (170° conical) allowing larger areas to be adequately covered by fewer speakers.

An integrated, steel enclosure provides up to 20dB of noise reduction on the back of the speaker. The IS4 C frame is constructed from extruded aluminum. Connection is made via a barrier strip that is covered with a steel plate that features a connection point for 1/2" conduit.

The IS4 C is transformer-coupled, with 32W, 16W, 8W, 4W, 2W, 1W, .5W taps and 8-ohm bypass that are selectable from the speaker’s enclosure.
