Definitive Technology DC-65 MAX 6.5" In-Ceiling Speaker

Ceiling speakers usually aim straight down, and the Definitive Technology Dymension DC-65 MAX pivots both its 6.5 inch woofer and its 1 inch tweeter so sound can be directed toward the seats.

The mineral-filled poly woofer uses a Linear Response Waveguide, a three-way high-frequency switch tunes the highs, the micro-perforated magnetic grille is paintable, and IP55 protection suits humid or covered outdoor spaces.
