Definitive Technology DI 3.5R Disappearing Series Round 3.5″ In-Wall / In-Ceiling Speaker

Definitive Technology DI 3.5R In-Wall/Ceiling Speaker

The DI 3.5R from Definitive Technology is a 2-way in-wall/ceiling speaker engineered for exceptional audio performance in a minimal footprint. Its 3.5-inch Balanced Dual Surround System (BDSS) mid/bass driver delivers deep, dynamic sound, while the 0.75-inch pivoting dome tweeter allows precise aiming of high frequencies for optimal listening. The speaker’s flangeless, low-profile, paintable magnetic grille ensures it virtually disappears into walls or ceilings, maintaining a clean and seamless aesthetic. The PolyStone basket provides rigidity, minimizing vibrations and resonance for clearer sound. With a frequency response of 40 Hz to 30 kHz, nominal impedance of 8 ohms, and sensitivity of 89 dB, the DI 3.5R is compatible with a wide range of amplifiers. Axial alignment ensures balanced coverage across the listening area, and the spring-loaded heavy-duty inputs make installation simple. This discreet speaker is ideal for small spaces, surround sound setups, or multi-room audio systems, delivering powerful sound without drawing attention to its presence.
