Definitive's UIW 83/A in-ceiling speaker features a high output 8 inch driver and 1 inch pure aluminum dome tweeter perfectly blended with a complex phase-coherent Linkwitz-Riley crossover network. The UIW 83/As are perfect for front, surround and center channel use in stealth home theater systems or for producing exceptional sounding music throughout your home.

Easy-to-Install
One hole, no mess. Precision templates are included to make cutting the right size hole a breeze even for weekend warrior DIY. Locking arm mounting system grabs your wall with high tension clamps at the turn of a screw, stiffening the baffle and eliminating resonance (Rough-In Kits for new construction are available, too.) UIW 83/As are easy to paint so they virtually disappear into your room, and moisture-resistant for kitchen and even bathroom installations.

Pure Aluminum Dome Tweeters
Exclusive magnetic fluid-cooled moving-coil tweeter dome of Pure Aluminum brings together the performance advantages of metal domes (greater clarity) and soft domes (smoother sound and better dampening) in one state-of-the-art tweeter design, for detail, clarity and accurate imaging.

High-Definition Bass/Midrange Drivers
Aerodynamically designed, magnetically inert baskets minimize reflections of the sound radiating from the back of the cones and preserve structural and magnetic integrity for significant performance advantages in the areas of bass reproduction, lifelike midrange clarity and dynamic range.

Rigid Non-Resonant Glass-Filled Low Profile Frames
Molded of a glass-filled polymer compound to eliminate baffle resonance, the UIW 83/A's frame maintains sonic purity by defeating diffraction, giving it a wide, dynamic sound stage with minimized resonance or coloration.
