Installing quality in-ceiling speakers doesn't have to be difficult! This pair of Yamaha NS-IC400WH 4 In. 90 Watt Max In-Ceiling Speakers are easy to install thanks to the large mounting clamp with nonslip tread for sure grip. Plus they have paintable magnetic grilles, making them ideal for various custom installation requirements, including in-wall. Each speaker also features Yamaha's original double-layer 4 in. cone that creates natural sound tonality, a ridge-shape aluminum center cap with stair-like speaker surround that helps smooth frequency response from low to high, a sealed back cover to protect speaker and crossover from dust and moisture, and a grain-finished acoustic baffle with spiral pattern for natural sound dispersion.
