    • Peak Power Handling: 200 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
    • Impedance: 8 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
    • Minimum Frequency Response: 26 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)

The device supports high-resolution audio signals, which more closely resemble the quality of music as it was originally recorded, with more texture and detail than can be heard via typical music streaming services or CDs.)

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.

      Excellent sound, installation was easy

      I started shopping for these almost a year ago when our house was under construction. I went to Best Buy to compare their in ceiling speakers. The Best Buy person recommended Sonance speakers, but the DI 6.5Rs just sounded much better. I felt the Sonance MAG series speakers sounded very muddy. I ended up buying 4 of these for the great room. First, installation was a breeze. I was a little nervous taking a drywall saw to my new ceiling, but the template made things simple. I had run the speaker wires before the drywall went up, so that part of the task was already complete. I did use, and highly recommend, XTC 10 inch speaker baffles that create a protective cavity in the ceiling. With the holes cut, the baffles in place, the speakers just slid into place and the 4 tabs are holding the speakers nice and snug. Just don't overtighten the screws. The magnetic grills snapped into place, leaving a clean, stealthy installation (see photo). I hooked these up to a Yamaha RX-V4A. Not the highest end AVR, but acceptable for my needs in this room. The sound is already good and I am sure that will improve as they break in. My only concern is the bass. As you can see from the photo, the room is rather large. I am considering adding a subwoofer. I am not a big bass person, I keep my subwoofer in my theater room pretty low. I just feel a subwoofer will help these speakers fill the room with the low end. Overall I am very happy with these speakers and I will be installing two more of these as my Atmos height speakers in my theater room. I knocked off 1 star in value, due to the price. Perhaps it was the sticker shock of buying four of these at once.
