Short answer: the JBL L52 Classic, since the Q Acoustics 3020i measures worse than it looks, though neither ranks well in its class. The 3020i is styled well, with recessed binding posts and custom connectors, but its on-axis response rises toward the top, dips through the 2-4kHz crossover region and shows two resonance-related dips, including a significant one at 366Hz in the waterfall plot. The L52’s compression and distortion from about 1-5kHz remain inconsistent, so expect flaws either way. 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 still sold new, while the Q Acoustics 3020i is discontinued.

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 3020i: $314.99 per pair Discontinued eBay
Newer model: the Q Acoustics 3020c. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. Vertical directivity is good enough that the tweeter doesn’t need to be exactly at ear level. With EQ correction, especially high-frequency shelving and a sub-40Hz high-pass filter, Amir found performance “improves substantially.”. Measured bass extension of 82.0Hz (-3dB).
Cons: On-axis response shows a rising upper-frequency trend and a dip in the 2-4kHz crossover region alongside two resonance-related dips; a significant resonance appears at 366Hz in the waterfall plot. Horizontal directivity is narrow and uneven due to a woofer/tweeter beamwidth mismatch. Amir cautions the speaker is “merely a distortion generator” if played too low, and its low impedance demands a quality amplifier. Without EQ, Amir “can’t recommend the Q Acoustics 3020i.”. Discontinued; Q Acoustics now sells the 3030i and 3010c in its place.
