#83 PSB Alpha P3: $349.00 per pair Amazon PSB Speakers eBay
Same family: the PSB Alpha P5 (larger bookshelf, ranked higher, rated 3.6/5), the PSB Alpha T20 (floorstanding, estimated 3.9/5) and the PSB Alpha C10 (center, estimated 3.4/5).
Pros: Very compact cabinets still reach about 55Hz in the local Spinorama snapshot, while the 5.64 sub-assisted score and relatively smooth sound-power behavior make this a sensible small-room speaker. Magnetic grilles and binding posts add practical polish. Measured bass extension of 63.0Hz (-3dB).
Cons: Low measured sensitivity around 81dB restricts clean output and asks more of the amplifier. The raw 3.12 preference score and some response/directivity irregularity keep it behind the best modern compact monitors, and a subwoofer is strongly recommended.
