#46 PSB Alpha P3: $449/pair PSB Speakers eBay

Pros: Very compact cabinets still reach about 55Hz in the local Spinorama snapshot, while the 4.85 sub-assisted score and relatively smooth sound-power behavior make this a sensible small-room speaker. Magnetic grilles and binding posts add practical polish.

Cons: Low measured sensitivity around 81dB restricts clean output and asks more of the amplifier. The raw 2.33 preference score and some response/directivity irregularity keep it behind the best modern compact monitors, and a subwoofer is strongly recommended.

How it compares: Just above it: Monitor Audio Apex A10 - $400 more, 2Hz higher bass extension (-3dB). Just below it: ELAC Debut 2.0 B5.2 - $120 cheaper, 2Hz lower bass extension (-3dB).
