Built-in speaker Yamaha NS-IC400 White

Yamaha NS-IC400 in-ceiling speakers with magnetic grilles for custom installations

The NS-IC400 is a pair of ceiling speakers designed for permanent installation into suspended ceilings, where they serve as front or surround channels. The design is based on a full range open back driver, which uses the ceiling cavity itself as the acoustic space, simplifying installation without the need for a separate enclosure. Magnetically attached grilles allow installation without visible fixings and easy removal for servicing.

At the heart of the system is a 4" driver with a dual-layer cone, covering the 95 Hz – 40 kHz range without a crossover in the main signal path. The sensitivity of 85 dB (2.83 V / 1 m) and 8 ohm impedance suit common amplifiers and installation amplifiers, with a maximum power handling of 90 W. The 3-1/8" mounting depth and weight of 1.76 lb per unit reduce the demands placed on the ceiling structure.

A full-range solution without band splitting contributes to phase consistency and stable source localisation, which matters with ceiling placement for vocal intelligibility and smooth transitions between channels. A response extending to 40 kHz supports the legibility of upper harmonics, while the lower limit of 95 Hz assumes the addition of a subwoofer for full-range use. Supplied with a paintable grille with a protective cover, allowing it to be matched to the ceiling colour.
