Yamaha NS-IW660 In-Wall Speakers – Pair (White)
Description
High-Performance 3-Way In-Wall Sound
The Yamaha NS-IW660 In-Wall Speakers deliver detailed, high-performance sound from a discreet custom installation. Each 3-way speaker combines a 6.5-inch Kevlar cone woofer, 1-5/8-inch aluminum-dome midrange driver and 1-inch titanium-dome tweeter, providing a wide 50Hz–28kHz frequency response.
With 50W nominal and 150W maximum input power, 8-ohm impedance and 88dB sensitivity, the NS-IW660 is designed for use with compatible AV receivers and amplifiers in home theater and custom-installed audio systems.
Aim the Sound Toward Your Listening Area
Both the midrange driver and tweeter can be swiveled, allowing the higher frequencies to be directed toward the main listening position. A high-frequency level adjustment also helps tailor the speaker's response to your room, placement and listening preferences.
Yamaha's customized crossover network is designed to minimize distortion and maintain clean, natural transitions between the woofer, midrange and tweeter.
Designed for Custom Installation
The NS-IW660 features a compact 3-1/16-inch mounting depth, gold-plated push-type speaker terminals and a paintable grille and frame for a clean, low-profile installation. Yamaha recommends the NS-IW660 for in-wall front and surround speaker applications, making it a versatile choice for discreet home theater systems.
