Short answer: the Philharmonic Ceramic Mini. It ranks #2 of 87 bookshelf speakers by sound quality at $900; the Q Acoustics 5020 ranks #73 and costs $1199, so there is little reason to consider the other one.
What the Philharmonic Ceramic Mini offers: Gorgeous looks and finish options for the price. Very low midrange distortion for the size, well under 1% above about 400-500Hz. Excellent on-axis linearity. Mild, pleasant bass bump around 100Hz that adds welcome warmth without being excessive. Wide soundstage and dispersion (~70-80 degrees horizontally). Clean cabinet and port with no measured resonances. A great value combination of looks and performance at this price. Watch for: 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. A mild diffraction-related dip around 4-6kHz can cause occasional sibilance on some vocal tracks. Measured sensitivity (82.2dB average) runs a bit below the manufacturer’s claimed 84dB, so it needs more amp power than the spec alone suggests. Needs a subwoofer for real bass authority below about 40Hz.
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.
Buy the Philharmonic Ceramic Mini. It ranks higher for sound quality than the Q Acoustics 5020 and costs less, so there is no real case for the other one.
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.
