Short answer: the JBL Studio 630. It ranks #52 of 84 bookshelf speakers by sound quality at $699; the Chesky LC1 ranks #80 and costs $1000, so there is not much of a tradeoff to weigh.
What the JBL Studio 630 offers: Excellent directivity linearity: harmonics of the same instrument stay collocated in the soundstage instead of drifting between positions, giving precise, stable imaging that holds up well into higher frequencies where many… Watch for: Noticeable mid-range dip/scoop relative to the higher frequencies - not dramatic, but audibly “missing” something by the second or third track.
What the Chesky LC1 offers: Premium build details: silver-soldered crossover with film capacitors, dual inertially-balanced 8” passive radiators, and a multi-layer, non-resonant cabinet construction. Watch for: Overall tonal balance sounded dull, hollow, and unengaging in extensive listening, with recessed vocals (both male and female) and minimal bass - the reviewer independently confirmed the same impressions auditioning the speakers…
Buy the JBL Studio 630. It ranks higher for sound quality than the Chesky LC1 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Chesky LC1. It ranks near the bottom of the 84 bookshelf speakers, so look higher up the list instead.

JBL Studio 630: $699 Amazon
Pros: Excellent directivity linearity: harmonics of the same instrument stay collocated in the soundstage instead of drifting between positions, giving precise, stable imaging that holds up well into higher frequencies where many speakers start to beam and narrow. Good compression behavior - mid-bass stays taut and controlled from low to high volume without the sound falling apart or distorting as you turn it up. A pleasant, controlled mid-bass bump in the 60-100 Hz range adds punch to kick drums without bleeding into an uncontrolled boom on bass guitar. Horizontal radiation holds steady off-axis (about ±60°), so toe-in isn’t fussy. Compared directly to its predecessor, the JBL Studio 530, the reviewer would pick the 630 - smoother trend line through the upper mids and treble, and likely more dynamic headroom - as long as you’re willing to EQ.
Cons: Noticeable mid-range dip/scoop relative to the higher frequencies - not dramatic, but audibly “missing” something by the second or third track. Some tracks read as forward or aggressive around 2 kHz, like the upper frequencies are jumping out at you rather than sitting in stage depth. Needs EQ to bring the mid-range back up to be fully recommendable; without EQ available, the reviewer says he’d look at a different speaker entirely. Measured sensitivity (about 83.2dB) runs noticeably below the 85dB manufacturer spec, likely a byproduct of the mid-range dip skewing the average downward.

Chesky LC1: $1000 Discontinued
Pros: Premium build details: silver-soldered crossover with film capacitors, dual inertially-balanced 8” passive radiators, and a multi-layer, non-resonant cabinet construction. Wide horizontal radiation of about ±60-70° through the midrange, in the reviewer’s preferred range. Extremely easy to drive electrically (minimum impedance about 8.4 ohms, minimum EPDR 5.4 ohms). Distortion shows good separation between second- and third-order harmonics at both 86dB and 96dB. The reviewer took the unusual step of verifying his measurements weren’t due to a defective unit - he impedance-swept both speakers, then corresponded directly with the manufacturer, whose own measurements matched his, confirming the sound reflects the actual product design.
Cons: Overall tonal balance sounded dull, hollow, and unengaging in extensive listening, with recessed vocals (both male and female) and minimal bass - the reviewer independently confirmed the same impressions auditioning the speakers at an audio show, ruling out a fluke with his own pair. Essentially no meaningful bass below about 90-100Hz in-room (F3 71Hz, F10 49Hz), well short of the 50Hz frequency-response spec, and measured sensitivity (about 81.4dB) runs well below the 86dB claimed. A pattern of peaks and dips across the spectrum, rather than a simple tilt, makes different instruments sound inconsistent depending on what frequency range they occupy - an unusually difficult profile to characterize or EQ around. Center-image focus never locked in properly regardless of listening position - traced to a measurable mismatch between the two individual speaker samples’ on-axis response, an unusual quality-control issue for a simple dome-tweeter design. A cancellation/lobing region just below the tweeter axis, likely from shallow first-order crossover slopes and some crossover-region overlap, means listening position needs to stay right at or slightly above tweeter level. Elevated multitone distortion in a region tied to a cone-edge/surround resonance (a known issue across several driver brands), only marginally improved by adding a subwoofer. Sample-to-sample driver measurements showed real inconsistency between the two review units’ tweeters and midwoofers. A cosmetic gap around the tweeter’s flush-mount cutout suggests room for tighter fit-and-finish. Discontinued.
