Short answer: the PSB Imagine T65. It ranks #24 of 54 floorstanding speakers by sound quality at $2699; the Klipsch Heresy IV ranks #32 and costs $3198, so there is not much of a tradeoff to weigh.
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. 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.
What the Klipsch Heresy IV offers: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement—well below Klipsch’s 99dB in-room claim, but still excellent—and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. Watch for: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction.
Buy the PSB Imagine T65. It ranks higher for sound quality than the Klipsch Heresy IV and costs less, so there is no real case for the other one.

PSB Imagine T65: $2,699 The Audio Factory
Pros: 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.
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.

Klipsch Heresy IV: $3,198/pair Amazon Crutchfield
Pros: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement—well below Klipsch’s 99dB in-room claim, but still excellent—and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. The compact, furniture-grade Heritage cabinet is easier to place than most high-efficiency designs, and dynamics at moderate levels can sound lively. A stable four-ohm-capable amplifier can produce substantial SPL with relatively little voltage.
Cons: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction. The impedance dips to about 4 ohms, reducing the practical amplifier advantage implied by its sensitivity. Pronounced directivity mismatch at the driver transitions, impedance/response resonances and elevated distortion spikes around the crossover remain audible concerns that EQ cannot fully solve. At 102dB Erin measured roughly 1.5dB midband compression; at 96dB distortion rises around crossover. Performance is difficult to justify at the price, and Erin explicitly did not recommend it.
