Product Details

Definitive Technology DT Series 8" White 2-Way In-Ceiling Speaker - DT8R

Every element of the DT8R is optimized for superior quality and sound. Each part is developed from scratch for a listening experience that delivers and a product that endures. The DT8R is simply the best sounding in-ceiling speaker for multi-room and home theater applications all things considered. Great performance, invisibility and ease of installation are why it endures.

Key Features:

  • Exclusive 8" composite mineral-filled polypropylene driver cones offer superior transparency
  • Annealed aluminum tweeter dome provides great transients and smooth response
  • High definition crossover network with Mylar capacitors delivers the purest high frequencies
  • Improved sound dispersion and off-axis response casts incredible sound throughout the room


  • Premium Materials for Optimized Audio
    DT Series speakers use exclusive composite-filled polypropylene driver cones with rubber surrounds for superior transparency and longevity
  • High Definition Crossover
    Crossover is crucial to high-end audio quality. The high definition crossover network in DT Series speakers is how each one delivers the purest high frequencies
  • Annealed Aluminum
    Great transients and smooth response are the direct result of the perfect rigidity and lightness of an acoustically optimized annealed aluminum tweeter dome
  • Designed for Superior Sound
    Speakers that visually dominate the room distract from the sound. DT Series speakers have whisker-thin micro-perf grilles with slim bezels that can be custom painted to blend in
