Short answer: the ELAC Debut 2.0 B5.2. It ranks #24 of 56 bookshelf speakers by sound quality at $329; the JBL L52 Classic ranks #34 and costs $1099.95, so there is not much of a tradeoff to weigh.
What the ELAC Debut 2.0 B5.2 offers: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Watch for: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance.
On the JBL L52 Classic side: Genuine walnut wood veneer cabinet with a retro Quadrex foam grille (black, orange, or dark blue) reviving JBL’s classic L-series look. Set against that: Measured compression and distortion behavior from about 1-5 kHz was inconsistent (“wonky”) across output levels, and didn’t clean up even at lower volume.
Buy the ELAC Debut 2.0 B5.2. It ranks higher for sound quality than the JBL L52 Classic and costs less, so there is no real case for the other one.

ELAC Debut 2.0 B5.2: $329.00 Amazon
Pros: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system.
Cons: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger B6.2 instead when EQ is unavailable.

JBL L52 Classic: $1,099.95 Amazon
Pros: Genuine walnut wood veneer cabinet with a retro Quadrex foam grille (black, orange, or dark blue) reviving JBL’s classic L-series look. 5.25” pure pulp cone woofer and 0.75” titanium dome tweeter on a waveguide, front-firing bass reflex port, in a compact stand-mount cabinet. A pronounced upper-bass bump around 100 Hz gives kick drums a punchy, textured character.
Cons: Measured compression and distortion behavior from about 1-5 kHz was inconsistent (“wonky”) across output levels, and didn’t clean up even at lower volume; adding a subwoofer high-pass didn’t fix the high-frequency distortion either. Response rolls off quickly above the upper-bass bump, so there’s punch and impact but not real low-end rumble or fundamental weight below about 60 Hz without a subwoofer. Soundstage width was inconsistent track to track, with imaging not staying locked to where instruments should be. Vocals could sound hot and slightly grainy in the 2.5-5 kHz region; pointing the speakers off-axis reduced that sharpness but also killed high-frequency air.
