Short answer: the Revel M105 for better sound quality, the Q Acoustics 5020 for the lower price. The Revel M105 ranks #13 of 87 bookshelf speakers at $1500. The Q Acoustics 5020 ranks #73 at $1199, $301 cheaper.
What the Q Acoustics 5020 offers: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Erin found distortion well controlled at normal levels: below 1% down to about 50Hz at 86dB/1m. Its 87dB measured sensitivity is unremarkable rather than hard to drive, and it maintains acceptable output for typical 80-85dB listening. The rear port can be plugged for placement flexibility. Watch for: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range. The shallow woofer crossover and steeper tweeter slope contribute to the off-axis discontinuity, while the port has a strong 1kHz resonance. Bass is limited: Erin measured F3 103Hz and F10 48Hz; at 96dB distortion reaches about 3% by 100Hz, and he bottomed the woofer when pushed hard. He preferred the less-expensive 3020i’s linearity and did not recommend the 5020 for neutral listening without EQ.
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 Q Acoustics 5020 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 Q Acoustics 5020. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
