Short answer: the Revel M105 for better sound quality, the Micca RB42 for the lower price. The Revel M105 ranks #13 of 87 bookshelf speakers at $1500. The Micca RB42 ranks #72 at $159.99, $1340.01 cheaper.
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.
What the Revel M105 offers: CEA2034 spinorama shows an essentially flat on-axis response with only a small 5kHz peak, a smooth listening window, and clean waterfall decay. Wide horizontal dispersion gives flexibility with toe-in. The reviewer called it reference-quality performance with minor EQ correction applied. Watch for: Low nominal impedance demands a capable amplifier that can handle low-impedance loads. Bass distortion runs high in the 80-250Hz range from woofer displacement, and maximum output is limited compared to larger designs.
Buy the Micca RB42 if the price matters more than sound quality. Buy the Revel M105 if sound quality matters more than the price.
If sound quality matters at all to you, skip the Micca RB42. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
