Short answer: the PSB Imagine T65 for better sound quality, the Infinity Reference 253 for the lower price. The PSB Imagine T65 ranks #34 of 71 floorstanding speakers at $2699. The Infinity Reference 253 ranks #60 at $400, $2299 cheaper.
What the PSB Imagine T65 offers: Three-way design with dual 6.5” woven carbon fiber woofers delivers genuinely strong, extended low end for a $2,699 tower - among the better performers Erin has measured in this price class. Distortion shows a clean second-order character with clear separation from third-order all the way up to 96 dB, indicating a well-controlled motor. Compression data shows enhancement rather than compression below about 50-60 Hz, so the bass can sound louder as you turn it up rather than choking off. Wide, forgiving vertical listening window (about ±25°) thanks to the 3-way layout, giving more seating and placement flexibility than most towers. Plenty of dynamic headroom for home theater use or a two-channel system - 100W drove it comfortably in Erin’s room. Watch for: Noticeable dip in the midrange/crossover region that Erin flagged as affecting dialogue and vocal clarity, though he notes a couple bands of EQ smooths it out. Some horizontal dispersion mismatch (about 10-15° of ballooning between 1-3 kHz) between the midrange and tweeter can add extra perceived attack or detail if your room’s sidewalls are reflective. Dips to 4 ohms, so it wants an amplifier comfortable driving a 4-ohm load. Distortion climbs above 3% around 60 Hz at 96 dB, though it’s benign second-order distortion.
What the Infinity Reference 253 offers: Horizontal beamwidth of about ±60 degrees is fairly smooth and well controlled. Really amazing value for the performance. Watch for: CEA2034 spinorama and predicted in-room response both show elevated treble above 4kHz (“too hot”), a dip around 2kHz, and bass shelved down relative to the midrange. Vertical directivity requires staying at or below the tweeter axis for accurate tonal balance. Distortion at 96dB SPL/1m is broadly elevated above the reviewer’s audibility threshold across much of the midrange. Minimum impedance dips to 4.2 ohms.
Buy the PSB Imagine T65 if sound quality matters more than the price. Buy the Infinity Reference 253 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Infinity Reference 253. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
