Short answer: the JBL L52 Classic, though neither ranks well in its class. It ranks #65 of 88 bookshelf speakers by sound quality, rated 2.6/5, at $999; the Q Acoustics 5020 ranks #74, rated 2.2/5, and costs $1,199, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 88 bookshelf speakers, and the Philharmonic Ceramic Mini, ranked #2 at $900, is a better place to start if sound quality matters.
What the JBL L52 Classic does well: Genuine walnut wood veneer cabinet with a retro Quadrex foam grille (black, orange, or dark blue) reviving JBL’s classic L-series look. The tradeoff: 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.
What the Q Acoustics 5020 does well: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. The tradeoff: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range.
Buy the JBL L52 Classic. It is rated higher for sound quality than the Q Acoustics 5020 and costs less, which makes it the one to get unless you need something the other one does better.

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.

Q Acoustics 5020: $1,199.00 per pair Amazon eBay
Pros: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Erin found distortion well controlled at normal levels: below 1% down to about 50Hz at 86dB/1m. Its 87dB measured sensitivity is unremarkable rather than hard to drive, and it maintains acceptable output for typical 80-85dB listening. The rear port can be plugged for placement flexibility. Measured bass extension of 103Hz (-3dB), with a measured sensitivity of 87.1dB.
Cons: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range. The shallow woofer crossover and steeper tweeter slope contribute to the off-axis discontinuity, while the port has a strong 1kHz resonance. Bass is limited: Erin measured F3 103Hz and F10 48Hz; at 96dB distortion reaches about 3% by 100Hz, and he bottomed the woofer when pushed hard. He preferred the less-expensive 3020i’s linearity and did not recommend the 5020 for neutral listening without EQ.
