Short answer: a tradeoff: the ELAC Uni-Fi 2.0 UB52 measures more predictably, the JBL L52 Classic has the classic looks, though neither ranks well in its class. The UB52’s wide, smooth horizontal directivity holds to about plus or minus 60 degrees up to 8kHz, though it dips 3dB between 1.5-3kHz. The L52’s walnut veneer and Quadrex grille are the draw, but its compression and distortion from about 1-5kHz were inconsistent across output levels and never cleaned up at lower volume. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Philharmonic Ceramic Mini ranks #2 at $900.
Buy the JBL L52 Classic. It is rated higher for sound quality, and the $200 you would save on the ELAC Uni-Fi 2.0 UB52 does not close the gap.

The Two Speakers In Full
JBL L52 Classic: $999.00 per pair Amazon eBay
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. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 85dB.
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.

ELAC Uni-Fi 2.0 UB52: $799.00 per pair Amazon eBay
Pros: Wide, smooth horizontal directivity: beamwidth holds to about ±60 degrees up to 8kHz before narrowing. Vertical directivity is substantially better than average, giving more listening-height leeway than most two-way bookshelf speakers. Measured bass extension of 55.7Hz (-3dB), with a measured sensitivity of 83.3dB.
Cons: Dipped 3db from 1.5-3kHz. On-axis response shelves down above 1.5kHz along with multiple resonances, leading the reviewer to predict it will “likely sound dull.” Nasty resonance at 600Hz: audible as an actual buzzing artifact on some recordings (the reviewer demonstrated it with an Eva Cassidy track), and it shows up as a sharp distortion spike exceeding 4% at 585Hz when driven to 96dB SPL/1m. Not recommended.
