Short answer: the Klipsch Forte IV. It ranks #101 of 188 floorstanding speakers by sound quality (rated 4.0/5) at $5,499.98 and is still sold new; the JBL Studio 590 ranks #178 (rated 2.8/5) and is discontinued, so it is only an option used. The JBL Studio 590’s replacement, the JBL Studio 698, is rated 4.3/5.
The Klipsch Forte IV is the better-sounding pick. 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. The tradeoff: 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.
The JBL Studio 590 is the more accurate, deeper-bass option. Pretty deep bass. Its measured preference score, a predictor of how neutral it sounds, is 4.49 against 3.78 for the Klipsch Forte IV. Its bass reaches about 48Hz before falling 3dB, against 82Hz for the Klipsch Forte IV. Watch for: 3dB peak at 1.7kHz, about a 4dB peak from 8k to 13k, going to be bright up top.
Buy the Klipsch Forte IV. It is rated higher for sound quality, and the JBL Studio 590 is discontinued, so it is only available used.

Klipsch Forte IV: $5,499.98 per pair Amazon Crutchfield eBay
Same family: the Klipsch Heresy IV (smaller floorstanding, ranked lower, rated 2.3/5), the Klipsch Cornwall IV (larger floorstanding, ranked lower, estimated 2.8/5), the Klipsch La Scala AL6 (larger floorstanding, ranked lower, estimated 2.8/5) and the Klipsch Klipschorn AK7 (larger floorstanding, ranked lower, estimated 3/5).
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 Klipsch Heresy IV in the same lineup. Surprisingly wide, expansive soundstage that beat both the Klipsch Heresy IV and a KEF LS50 Wireless 2 in direct comparison: images occasionally appeared several feet outside the physical speaker location. Deeper bass extension than the Klipsch Heresy IV (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.

JBL Studio 590: $2,000 per pair Discontinued eBay
Newer model: the JBL Studio 698, ranked higher, rated 4.3/5.
Same family: the JBL Studio 530 (bookshelf, rated 3.3/5) and the JBL Studio 520C (center, rated 3.4/5).
Pros: Pretty deep bass. CEA2034 spinorama is flat on-axis at a high level, with high sensitivity around 89-90dB. Predicted in-room response is good aside from a dip between 800Hz-1.5kHz. Distortion at 86dB SPL/1m is good outside of the 8.5kHz resonance. Measured bass extension of 48Hz (-3dB), with a measured sensitivity of 90.3dB.
Cons: 3dB peak at 1.7kHz, about a 4dB peak from 8k to 13k, going to be bright up top. Just okay vertical off axis. Really bad resonance at 8.5kHz, which shows up as a sharp distortion spike at both 86dB and 96dB SPL/1m. Cumulative spectral decay (waterfall) reveals many fine resonances across the midrange and treble. At 96dB SPL/1m the midrange and treble get notably messier, with broad distortion elevation from 2-8kHz. Discontinued.
