About the Q350
The KEF Q350 is a two-way bass-reflex bookshelf speaker from the Q Series. It uses KEF’s 165 mm (6.5-inch) aluminium Uni-Q driver array with a 25 mm (1-inch) vented aluminium dome tweeter positioned in the centre of the mid/bass driver. Its Computational Fluid Dynamics (CFD) port is designed to reduce turbulence and distortion for cleaner, more controlled bass. The Q350 has a 63 Hz–28 kHz frequency response (±3 dB), a 42 Hz low-frequency extension at -6 dB, 87 dB sensitivity, and is recommended for amplifiers rated at 15–120 watts. Available finishes include Black, White, and Walnut, depending on market.
