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.
