The NS-IC400 from Yamaha is a compact in-ceiling speaker ideal for discreet installations in home theaters, bedrooms, living rooms, and more. The coaxial 2-way speaker design has a 4″ blue polypropylene mica cone woofer and a fluid-cooled soft dome tweeter to provide clear audio with a wide frequency response. The tweeter can be swiveled for precise aiming and the most effective high frequency output. The grille is paintable and has integrated magnets for quick attachment or removal. The speaker has a large mounting clamp with non-slip tread to firmly grip walls or ceilings for secure installation.
