3-Way Speaker Design
With separate tweeter, mid-range, and bass drivers, the Uni-Fi UB52 delivers clean bass without distorting vocals.

Newly Developed Concentric Driver
A new wide-surround tweeter enhances its low and high frequency extension, allowing for improved blending with the midrange driver. An entirely new mid-range design features a larger diameter voice coil, new aluminum cone profile, new low-profile surround, and an all-new neodymium magnet assembly.

New Single Piece Woofer
A newly developed single-piece aluminum dished cone results in improved stiffness. Combined with an oversized magnet, large diameter voice coil, and extended pole piece, these changes result in improved accuracy and bass dynamics.

Sophisticated 3-Way Crossover
An enhanced design improves response linearity, improves driver integration, and delivers a true 6-ohm nominal impedance for compatibility with virtually all AV receivers.

Enhanced Bracing
Every Uni-Fi 2.0 enclosure is engineered with thick MDF outer walls and a luxurious black ash vinyl finish. Specially located internal bracing adds stiffness and strength to the cabinet’s outer walls, reducing the cabinet vibration that causes unwanted coloration.
