Short answer: the Magnepan LRS+. It ranks #50 of 56 floorstanding speakers by sound quality at $1300; the JBL Studio 590 ranks #54 and costs $2000, so there is not much of a tradeoff to weigh.
The case for the Magnepan LRS+: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). The tradeoff: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output - a robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it.
What the JBL Studio 590 gets right: Pretty deep bass. The catch: 3dB peak at 1.7khz, about a 4dB peak from 8k to 13k, going to be bright up top.
Buy the Magnepan LRS+. It ranks higher for sound quality than the JBL Studio 590 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip both of these and look higher up the 56 floorstanding speakers instead.

The Two Speakers In Full
Magnepan LRS+: $1300 Magnepan
Pros: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). Delivers a uniquely dramatic and enveloping soundstage with genuinely three-dimensional depth effects that work across all music genres, not just classical or orchestral material as commonly assumed. Extremely tight, locked-in center-phantom imaging when set up correctly. Open-baffle design avoids the “boxy” enclosure coloration of conventional cabinet speakers. Multitone distortion is remarkably consistent from low to high frequency, a characteristic the reviewer hasn’t observed in conventional cone-and-dome speakers. Compression at high output stays modest (about 0.5-1dB) through the midrange and treble, giving roughly 20-26dB of usable dynamic range in that region. At its price, a strong contender for a dedicated secondary listening room, even if not a main-system replacement.
Cons: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output - a robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it. Bass rolls off very quickly (F3 74Hz, F10 67Hz, described as falling off “like a rock”), making a subwoofer an absolute requirement for any low-end content. A roughly 3dB dip in the mid-bass (100-300Hz) region thins out vocal body and fullness compared to a conventional bookshelf speaker. A resonance/bump around 400Hz adds a mild boxy quality, though it responds well to about 2dB of EQ correction. Extraordinarily fussy about exact positioning - both seating height (must align with the acoustic reference point between the panel’s lower tie-down points) and horizontal aiming are unusually critical; moving just a couple of inches can cause treble content above roughly 500-600Hz to nearly vanish. Distinct off-axis cancellation zones exist directly to the sides of the panel, where very little sound is audible at all. Fails badly under extreme dynamic-transient testing in the bass, and the reviewer blew fuses pushing the speaker during testing - not built for high-volume or highly dynamic playback. A genuinely different category from conventional hi-fi speakers, requiring more setup patience and experimentation than a typical monopole design.

JBL Studio 590: $2000 Discontinued
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.
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.
