Short answer: the JBL L52 Classic for better sound quality, the Micca RB42 for the lower price. The JBL L52 Classic ranks #34 of 56 bookshelf speakers at $1099.95. The Micca RB42 ranks #41 at $159.99, $939.96 cheaper.
What the JBL L52 Classic offers: Genuine walnut wood veneer cabinet with a retro Quadrex foam grille (black, orange, or dark blue) reviving JBL’s classic L-series look. Watch for: 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.
The case for the Micca RB42: Curved cabinet fit and finish look closer to a $400-500 speaker than a $150 one. The tradeoff: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up.
Buy the JBL L52 Classic if sound quality matters more than the price. Buy the Micca RB42 if the price matters more than sound quality.

The Two Speakers In Full
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.

Micca RB42: $159.99 Amazon
Pros: Curved cabinet fit and finish look closer to a $400-500 speaker than a $150 one. Rated for a wide 15-100W amplifier range with 4-8 ohm compatibility, giving flexibility with modest amplification.
Cons: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite an initial impression of “detail.” Off-axis response diverges heavily from on-axis, meaning tonality shifts with room and listening position in ways EQ can’t correct. Distorts and the woofer visibly flaps under moderate volume; low 83dB sensitivity makes it a harder amplifier load than its size suggests.
