Definitive Technology DI4.5R Disappearing In-Ceiling Speaker (Each)Extraordinary High-Performance Speakers that Virtually Disappear in Your Room!
Definitive's Disappearing In-Wall Speakers Just May be the "Holy Grail" of Built-in Speakers
You want great sound everywhere in your home, but you may not always have room for or want the visual intrusion of free-standing speakers. Built-in flushmount speakers seem to be the answer but in practice they don't exactly disappear in the room, in fact many "in-wall" speakers call attention to themselves and create friction between your decorator and your audiophile sensibilities. Worse yet, most built-in speakers fall short on the performance end as well. Would Definitive allow you to suffer with bad sound? Oh no, no, no.
Definitive's Disappearing® In-Wall series speakers feature near-invisibility thanks to their small diameters, hidden flange design, and low profile micro-perf grilles. They are as easy to install as traditional flanged flush-mount speakers, and don't require custom sheetrock/spackle skills to install yet they are practically invisible. The DI 4.5R 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.
Definitive's Advanced Technologies Mean Better Sound for You The Disappearing In-Wall models feature Definitive's most advanced technologies such as Balanced Dual Surround System (BDSS) mid/woofer drivers and pivoting Pure Aluminum dome tweeters for spectacular audio performance far beyond traditional flush-mount speakers.
Definitive's exclusive Balanced Dual Surround System (BDSS) driver technology permits these new flush mount speakers to deliver more bass output and dynamic range than larger drivers. For example, the DI 4.5R's 4-1/2" driver has the output, bass and dynamics of a 5-1/4" traditional speaker.
With a pivoting 1" Pure Aluminum dome tweeter featuring a specially shaped housing that avoids the diffraction distortions of traditional post-mounted tweeters, and a sophisticated adjustable crossover network, the Disappearing In-Wall models deliver the kind of lifelike sonic performance and broad even dispersion that have made Definitive Technology the most highly reviewed speaker brand in the USA.
Great Sound for Everyone in the Room
With in-ceiling speakers, listeners are almost always "off-axis." You rarely sit right under an in-ceiling speaker; usually the speaker is at a 30, 45 or even 60-degree angle to the listener. We've engineered DI Series speakers to disperse sound over a very wide area so that the sound is well-balance and natural regardless of where you are relative to the speakers. BDSS technology drivers, aimable tweeters as well as the specially countoured and textured AeroRing™ around the driver all contribute to the wide angle dispersion and superior coverage capability of the DI Series models.
Everything You Need for Installation
Optional pre-construction "rough-in" brackets with repositionable metal mesh "arms" are available for new home construction projects. Fire-rated pre-construction enclosures will be available as options, allowing integrators, architects and designers to specify Disappearing In-Wall Speakers in multi-family and commercial applications.
