Overview

Definitives in-ceiling DI 8R 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 8R grille is a mere 9-3/4 inches (24.8 centimeters) in diameter, noticeably smaller than competing 8-inch in-ceiling speaker.

Features

  • In-ceiling speaker
  • Simple to install, no spackle work required
  • Flangeless design and micro-perf grille minimize visibility
  • Perfect for use as side/rear surround speakers in home theater systems
  • Pivoting pure aluminum dome tweeters
