Definitive Technology DI 3.5R In-ceiling speaker

Enjoy rich, dynamic sound throughout your home without sacrificing an inch of floor space. Definitive Technology’s DI 3.5R speaker installs flush in your ceiling. It’s a great speaker for multi-room systems. Install a pair or two of these small speakers in a hallway or mud room, and use multiple pairs in a kitchen for well-balanced sound throughout the room. They’re the same size as many recessed track lighting fixtures. And each speaker is practically invisible, thanks to its paintable, low-profile grille and hidden flange.

The DI 3.5R pairs a pivoting 3/4″ aluminum tweeter with a 3-1/2″ driver for crystal-clear highs, solid bass, and impressive dynamic range. The pivoting tweeter allows you to aim the sound directly toward your listening area, so you can fine-tune your system’s sound.

An optional Definitive Technology Di 3.5R rough-in bracket is recommended for installing this speaker in new construction (brackets sold in pairs).

Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That’s because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality.
