The DI 4.5R Disappearing™ In-Wallspeaker features near-invisibility thanks to its small diameter, hidden flange design, and low-profile micro-perf grille. The DI 4.5R is a mere 53⁄8" (13.55 cm) in diameter, about the same size as the mini recessed lighting fixtures that are all the rage in lighting design today. It is as easy to install as traditional flanged flush- mount speakers, and doesn’t require custom sheetrock/spackle skills to install yet it is practically invisible when installed in a ceiling.

The DI 4.5R features Definitive’s most advanced technologies such as an advanced BDSS driver and pivoting Pure Aluminum Dome Tweeter for spectacular audio performance far beyond traditional flush-mount speakers.

Definitive’s exclusive Balanced Double Surround System (BDSS) driver technology permits the DI 4.5R to deliver more bass output and dynamic range than larger competitive 51⁄4" speakers.

With a pivoting 20mm Pure Aluminum Dome Tweeter, featuring a specially shaped Waveguide housing that avoids the diffraction distortions of bridge-mounted tweeters, and a sophisticated adjustable crossover network, the DI 4.5R Disappearing In-Wall delivers the kind of lifelike sonic performance and broad, even dispersion that have made Definitive Technology the leader in high-performance loudspeakers.

•Simple conventional installation — no spackle work required

•Latest generation BDSS Drivers for superior bass and dynamic range

•Pivoting Pure Aluminum Dome Tweeters ensure exceptional detail

•Axially aligned design ensures broad, balanced coverage area

•AeroRing™ damps resonance and improves off-axis sound quality
