Uni-Fi 2.0 UF52

Amplification Warning

A three-way tower with three 5.25-inch aluminium woofers and a concentric mid/tweeter, and the same 85 dB at 2.83 V as the UB52 bookshelf — the extra cone area goes into the 42 Hz bottom end, not into efficiency. The 200 Hz lower crossover puts the parallel bass array in charge of everything below the midrange, so this is a demanding load even before the unpublished minimum is considered. Do not pair it with a receiver rated only into 8 ohms.
