SKU

MPN:
DI4.5R

Overview

Definitives in-ceiling DI 4.5R 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 inches (13.55 centimeters) in diameter about the same size as the mini recessed lighting fixtures that are all the rage in lighting design today.

Features

  • Flangeless, ; flush mount design and micro-perf grilles allow 5.38" of visibility to match mini recessed lighting fixtures
  • Deeper sound quality with precision BDSS - drivers and a pivoting pure aluminum dome tweeter
  • Rigid PolyStone - baskets eliminate unwanted vibrations to prevent ringing and minimize distortion
  • Axially aligned design provides broader sound dispersion and more natural balance
