Definitive Technology DI 4.5R Overview
The Definitive Technology DI 4.5R In Wall/Ceiling Speaker is a flush-mount design that is perfect for multi-room audio systems. Its compact size and paintable low-profile grille make it virtually invisible. Its four-1/2" driver pairs with a pivoting 3/4" aluminum tweeter to deliver exceptional sound quality. Its slender design allows it to be installed in small spaces without the need for custom sheetrock work. Lastly, its specially contoured Aero Ring surrounds the speaker driver and provides a secure fit.
Definitive Technology DI 4.5R Features
The Definitive Technology DI 4.5R In Wall/In-Ceiling Speaker is an affordable, yet powerful speaker. With a five-inch visible diameter and a 4.5-inch mid-woofer, the DI 4.5R performs better than its larger counterparts. With its rich, immersive sound, the DI 4.5R is a versatile choice for any room in your home.
The DI 4.5R's 4.5" mid/bass woofer leverages DEFINITIVE's patented Balanced Dual Surround System (BDSS) to produce a wider area of sound. This technology helps deliver more bass while retaining the warmth and clarity of the lower-end frequencies.
