#52 PSB Imagine B50: $999 per pair PSB Speakers eBay
Same family: the PSB Imagine T54 (smaller floorstanding, estimated 4.2/5) and the PSB Imagine T65 (larger floorstanding, rated 4.3/5).
Pros: The standmount sibling to PSB’s Imagine T65 tower, from PSB’s current 2023-refreshed Imagine line, using the same titanium-dome tweeter and woven-carbon-fiber woofer platform. Measured bass extension of 69.6Hz (-3dB).
Cons: On-axis smoothness of just 0.235 and a deviation of 0.368dB are unremarkable for the price, with a +0.22dB per octave upward tilt giving it a brighter-leaning balance, a predicted in-room smoothness of just 0.35, and a Harman in-room bass extension estimate of only 49Hz. Current retail pricing ($999/pair) has risen well above the ~$700 figure recorded in the spinorama snapshot.
