Beyond the Bookshelf

Space constraints should never compromise great sound. The Uni-Fi 2.0 UB52 is the perfect solution when space is at a premium yet demand for audiophile sound is not negotiable. Using the same outstanding drivers and technology as the other models in the series ensures this compact, 3-way, bass-reflex monitor delivers a matched sonic signature.

The latest chapter in coherent concentric sound.

Improving upon the critically acclaimed  Uni-Fi series, the Uni-Fi 2.0 incorporates numerous changes that elevate the performance beyond the originals. In a complete redesign; from drivers to crossovers to cabinets, this new series redefines what is possible from a compact affordable loudspeaker.


  • Brand New Custom-Designed Concentric Driver
    A new wide-surround tweeter enhances it’s 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.

  • Newly Developed 5.25-inch Aluminum 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 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.

  • Robust Cabinets
    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.

  • Front Firing Ports
    Relocating the vents to the front on the bookshelf and center speakers allows for greater freedom of placement and closer placement to a rear wall.
