Short answer: the PSB Imagine T65, with the flaw you can actually fix. Its dual 6.5” carbon fiber woofers give genuinely strong, extended low end, among the better performers Erin has measured in this price class. The catch is a midrange/crossover dip that hurts dialogue and vocal clarity, though a couple bands of EQ smooths it out. The Forte IV is recessed in the 1.5-4kHz presence region instead, which can make tracks sound dull.
Buy the PSB Imagine T65. It is rated higher for sound quality than the Klipsch Forte IV and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.

Klipsch Forte IV: $5,499.98 per pair Amazon Crutchfield eBay
Pros: Three-way heritage design: a 1” titanium tweeter and 1.75” compression driver for the midrange mated to a 12” woofer, plus a 15” passive radiator for extra bass reinforcement. Genuinely resonance-free cabinet, a clear improvement over the notably boomy, resonant Heresy 4 in the same lineup. Surprisingly wide, expansive soundstage that beat both the Heresy 4 and a KEF LS50 Wireless 2 in direct comparison: images occasionally appeared several feet outside the physical speaker location. Deeper bass extension than the Heresy 4 (F3 of 82Hz, about 10Hz lower). Distortion measures well below 1% at 86dB and stays mostly within 1% even at 96dB. Comes as a factory-matched serial-numbered pair, backed by an unusually generous 10-year warranty. Mostly above 4 ohms impedance, so it’s compatible with AVRs, solid-state, or tube amplifiers. More neutral overall than other Klipsch models the reviewer has tested, making it a reasonable pick for listeners who already like the “Klipsch sound” but want something more balanced. Measured bass extension of 82Hz (-3dB), with a measured sensitivity of 93.8dB.
Cons: Contrary to the classic Klipsch reputation for being forward and bright, this model is actually somewhat recessed in the 1.5-4kHz “presence” region, which can make some tracks sound dull or lacking in detail. A peak around 6kHz reads as sibilant and “painful” when seated exactly on the tweeter axis; sitting a bit above that axis reduces it somewhat. Klipsch’s marketed 99dB sensitivity figure is an in-room rating that assumes 3-6dB of boundary gain: anechoic sensitivity measures closer to 94dB, which the manufacturer does disclose but can still mislead buyers comparing spec sheets. Radiation width isn’t consistent across all frequencies: a noticeable notch around 2-3kHz interrupts otherwise wide dispersion, which can cause a fundamental tone and its harmonics to image in slightly different places in the soundstage. Uses shallow low-pass crossover slopes (despite Klipsch’s steep-crossover marketing, which applies only to the high-pass side), likely contributing to some of the measured dips and possible cone-breakup artifacts. Some compression shows up around the midrange crossover point at very high output (102dB), though likely only audible at extreme volumes. At around $5500/pair, a significant investment, and still needs a subwoofer for material extending below about 50Hz.
