Short answer: it depends on which compromise you prefer. The PSB Imagine T65’s dual 6.5” carbon fiber woofers deliver genuinely strong, extended low end, but a midrange/crossover dip affects dialogue and vocal clarity. The Revel F35’s waveguide-loaded 1” aluminum dome tweeter and dual 5.25” mid-bass drivers are tidy, but its F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed.
Buy the Revel Concerta2 F35. It is rated higher for sound quality than the PSB Imagine T65 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Revel Concerta2 F35: $900 per pair Crutchfield eBay
Pros: Two-and-a-half-way, four-driver design: a 1” aluminum dome tweeter on a waveguide, a 5.25” mid-range, and dual 5.25” mid-bass drivers in a rear-ported cabinet. Measured sensitivity of 89.4dB closely matches the 90dB spec, and distortion looks good at both 86dB and 96dB, holding up well even with a high-pass filter applied. At its sale price of $900/pair, down from full retail, the reviewer calls it a “no-brainer,” undercutting comparable budget floorstanders like the ELAC DF63. Frequency response and directivity mismatches are largely EQ-able, since most of what shows up in measurements traces to physical tweeter/mid-range separation rather than a fundamental flaw. Compression is fairly well controlled for the price: about 1dB of loss around 100Hz under long-term compression, described as “par for the course” at this cost. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension. A dip in the lower midrange/2-3kHz region reduces attack and detail, and a peak around 5kHz adds some edge and sibilance in the lower treble. A peak in off-axis energy around 3kHz reflects off sidewalls at roughly 60-70° off-axis and arrives louder than the direct sound: this specific issue can’t be fixed with EQ (boosting the direct sound would boost the stronger reflection too) and would need acoustic absorption to properly address, though the reviewer considers it a minor, optional fix at this price. A couple of minor resonances appear in the impedance plot, including one around 300Hz that may partly explain a subtle sense of vocal warmth noticed in listening, though it’s more likely room-related. Minimum impedance around 3.8 ohms. Short-term compression testing shows some increased distortion in the tweeter and higher-frequency compression at loud output.

PSB Imagine T65: $2,699 per pair PSB Speakers eBay
Pros: Three-way design with dual 6.5” woven carbon fiber woofers delivers genuinely strong, extended low end for a $2699 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. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 85.1dB.
Cons: 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.
