The DI Series feature Definitive Technology's most advanced technologies such as BDSS 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 mounts to deliver more bass output and dynamic range than larger drivers. For example, the 4-1/2" driver-based model has the bass and dynamics of a 5-1/4" traditional speaker, while the 5-1/4" performs like a traditional 6-1/2". 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 DI Series delivers the kind of lifelike sonic performance and broad even dispersion that you've come to expect from Definitive Technology.

I bought 2 of these speakers to use as in-wall surround speakers in a 5.1.4 setup. These speakers sound great as surround speakers, but sound even better when playing music. During parties I set my Denon AVR-x6700h to all channel stereo and these little speakers play loud and clear. I wanted to get the 6.5r speakers, but unfortunately they did not fit in the area I wanted them because of stud placement. I bought the 4.5R because that is all I could fit, but was very pleasantly surprised when I heard out good these little speakers sound! If you have the room for the 6.5" or 8.5" speakers, obviously get those, but if you can't fit a bigger speaker, these will not disappoint!

Pretty good considering how small they are. Look super slick in the ceiling.

I bought these for overhead speakers for an Atmos set up. I didn't want to clutter up my ceiling with noticeable speakers and these were the smallest I could find. I wasn't loving the fact they aren't the same brand as the rest of my speakers but those would have been 2x as big. I didn't have the appetite for that, esp for basically sound effect speakers. Installed, they look tiny on the ceiling, but do not sound tinny. When sound is directed to them you can't even tell they are coming from the speaker. The sound is well distributed and matches my other speakers well enough.
