Definitive Technology DI 5.5R Disappearing Series Round 5.25″ In-Wall Loudspeaker

Definitive Technology DI 5.5R In-Ceiling Speaker

The Definitive Technology DI 5.5R is a high-performance, flush-mount in-ceiling speaker engineered for applications where minimal visual impact and superior audio quality are essential. Its 5.25-inch Balanced Dual Surround System (BDSS) mid/bass driver delivers deep, accurate low-frequency response, while the 1-inch pivoting pure aluminum dome tweeter allows precise aiming of high frequencies toward the listening area. This axial alignment provides broad, balanced sound coverage across the room. The micro-perforated grille is flangeless and paintable, maintaining a nearly invisible profile that blends seamlessly into ceilings or walls. With a wide frequency response from 28 Hz to 30 kHz, 8-ohm nominal impedance, and a sensitivity of 89 dB, the DI 5.5R accommodates peak power handling up to 175 watts. It is ideal for side or rear surround channels in home theater setups, as well as multi-room audio systems. The rigid PolyStone basket reduces resonance and distortion, while energy-absorbing baffle materials further enhance audio clarity. A high-definition adjustable crossover ensures smooth integration between drivers, and the GaussGrip magnetic grille fasteners along with the rotating clamp installation system simplify setup without requiring spackle or plasterwork. The DI 5.5R delivers a full, immersive audio experience while remaining almost invisible within your space.
