Utilizing a far-forward woofer mounted in a diminutive, small footprint frame together with two pole-mounted soft dome, lens-free tweeters, this excellent design avoids the diffraction & near-field boundary distortions that plague many other single point stereo in-ceiling loudspeaker designs.

  • Tuned for high fidelity and linear performance in standard drywall (ceiling) construction
  • System-concentric wide-field dispersion
  • Kevlar® fiber 6 1/2" (165 mm) dual voice coil, native yellow, square-woven woofer (DuPont) with butyl surround
  • Tetoron® 3/4" (19 mm) separate left & right pivoting soft dome, lens-free, woven-textile tweeters with neodymium motors
  • Audio grade polypropylene capacitor populated fiberglass board crossover circuit
  • Drivers wired with audio grade, high strand count, oxygen free copper, high current speaker cable
  • T-Stop signal-powered protection circuit prevents tweeter driver failure
  • Heavy spring-loaded gold-plated connection terminals accommodate up to 10 gauge speaker cable
  • White frame and grille is ready for mounting with a fine finished look; as well, it may be painted to match or accent mounting surface(s)
  • Rated for deployment in high humidity environments - fitted with stainless steel grille & mounting hardware
  • Includes nylon insulation isolating Top Hat. Top Hats "pop" into shape covering the top of the loudspeaker protecting it from ceiling/roof insulation material fibers & dust. Top Hats are acoustically "absent" in that they do not restrict cone excursion.
