Definitive Technology DI5.5S 5.25" 2-Way In-Wall Speaker - Each


Powerful performance is practically invisible with the Definitive Technology Disappearing™ Series. With a minimal 7.38” x 7.38” grille, the DI 5.5S is remarkably smaller than competing 6.5” models but offers much more in terms of technology and sound quality. From its 5.25” BDSS™ driver and 1” pure aluminum tweeter to the high definition crossover and exclusive AeroRing™, this in-wall side/rear surround speaker conceals tremendous tonality within its tiny dimensions.

  • Flangeless, flush mount design and micro-perf grilles allow a noticeably smaller 7.38” visible diameter
  • 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 provide broader sound dispersion and more natural balance
