No Framing, No Distractions

Flood the room with full, booming sound by installing the Preference 6.5 In. 15 Degree In-Ceiling Frameless Speaker, 2-Way (Single). Featuring widemouth baffle surfaces that are covered with Anti-Diffractional foam, this speaker is specially designed to produce exceptionally "open" and refined audio. The frameless speaker blends into the ceiling, and the grille can even be painted to match your decor.

  • Widemouth baffles produce "open", uninterrupted audio
  • Anti-Diffractional foam helps prevent sound distortion
  • Timbre-matching ensures a consistent tonal balance
  • Woven Kevlar woofers with butyl rubber surrounds
  • Tetoron soft dome pivoting tweeters
  • Mid/high frequency acoustic compensation/EQ switches

The Preference Standard

Every Preference model loudspeaker is "timbre-matched" ensuring sonic uniformity throughout the line. This means all models have been carefully engineered to have a family sound; this is also referred to as "voice matching."

As special effects from movie soundtracks move about the room, timbre-matching ensures a consistent tonal balance throughout the sound space. This creates that convincingly realistic three-dimensional spatial image, which completely absorbs the viewers into the cinematic experience. A home theater system may now consist of various loudspeaker sizes and shapes as dictated by room decor and layout, all the while delivering a seamless, transparent and coherent sound space.
