Short answer: the JBL Studio 530 for better sound quality, the Micca RB42 for the lower price. The JBL Studio 530 ranks #36 of 71 bookshelf speakers at $399. The Micca RB42 ranks #56 at $159.99, $239.01 cheaper.
What the JBL Studio 530 offers: CEA2034 spinorama shows a fairly flat on-axis response. Predicted in-room response is very smooth aside from the high-frequency roll-off. Watch for: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz. Response rolls off in the high frequencies and the tuning is a bit bass-shy overall. Cumulative spectral decay (waterfall) shows the same 1kHz-region resonances lingering in time.
What the Micca RB42 offers: 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. Watch for: 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.
Buy the JBL Studio 530 if sound quality matters more than the price. Buy the Micca RB42 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Micca RB42. It ranks near the bottom of the 71 bookshelf speakers, so look higher up the list instead.
