About the Uni-Fi UB5

The ELAC Uni-Fi UB5 is a three-way bass-reflex bookshelf speaker designed by Andrew Jones, featuring a custom-designed concentric driver that combines a 1" soft dome tweeter and a 4" aluminum midrange cone within a single voice coil for coherent and accurate midrange and treble reproduction. It includes a 5.25" aluminum cone woofer for midbass and bass frequencies. The speaker has a frequency response of 46 Hz to 25,000 Hz, sensitivity of 85 dB, and nominal impedance of 4 ohms. Its crossover points are at 270 Hz and 2700 Hz, ensuring smooth transitions between drivers. The cabinet is constructed from thick MDF with internal bracing to reduce vibration and unwanted coloration, finished in black brushed vinyl with magnetically attached cloth grilles. Dimensions are approximately 7.87" W x 12.75" H x 10.75" D, and each speaker weighs 16.5 lbs. It is recommended to be powered by amplifiers delivering 40 to 140 watts per channel. The UB5 is praised for its detailed midrange, controlled bass, and wide imaging, making it a standout compact three-way speaker at its price point.
