The DI 4.5R Disappearing™ In-Wall speaker features near-invisibility
thanks to its small diameter, hidden flange design, and low-profile
micro-perf grille. The DI 4.5
R is a mere 5
3
⁄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 4.5
R 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 4.5
R to deliver more bass output and
dynamic range than larger competitive 5
1
⁄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 4.5
R 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.
