The DI 4.5

R

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

" 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.
