Short answer: the Wharfedale Diamond 220 for better sound quality, the Micca RB42 for the lower price. The Wharfedale Diamond 220 ranks #27 of 74 bookshelf speakers at $350. The Micca RB42 ranks #59 at $159.99, $190.01 cheaper.
What the Wharfedale Diamond 220 offers: Amir found the on-axis response smooth once the grille is removed, calling grille removal “a huge improvement” since the stock grille caused unusually strong comb filtering around 5kHz. Good horizontal dispersion from the waveguide-loaded tweeter and controlled distortion. After some EQ (a room mode filter and treble shelf), the reviewer called it “a truly hifi speaker” where “every audiophile track…sounded very good,” and said he was “happy to recommend” it for the budget class. Watch for: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use. Some port rattling was noted at high volumes, traced to vibration rather than the woofer itself. Best performance requires removing the grille and applying the reviewer’s EQ filters.
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 Wharfedale Diamond 220 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 74 bookshelf speakers, so look higher up the list instead.
