Short answer: the Philharmonic Ceramic Mini. It ranks #2 of 179 bookshelf speakers by sound quality, rated 4.7/5, at $900. The Micca RB42 ranks #154, rated 2.3/5, at $159.99, $740.01 cheaper, which does not close the gap in sound quality.
The case for the Micca RB42: A budget bookshelf speaker with a curved cabinet that looks far pricier and works with a wide range of amplifiers. 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 seeming detailed at first.
The Philharmonic Ceramic Mini is the more accurate, deeper-bass option. A beautifully finished bookshelf speaker with near reference accuracy, low distortion, a touch of warmth and a wide soundstage. Its measured preference score, a predictor of how neutral it sounds, is 5.77 against 4.59 for the Micca RB42. Its bass reaches about 51Hz before falling 3dB, against 85Hz for the Micca RB42. The catch: Somewhat limited output capability for its size: audible woofer compression (“flopping”) around 95dB at 3 meters for a stereo pair, so keep to moderate levels or pair with a subwoofer for home theater use.
Buy the Philharmonic Ceramic Mini. It is rated higher for sound quality, and the $740.01 saving on the Micca RB42 is not enough to make up the difference.
