These are not really the same size class, and that is the honest framing here. The Q Acoustics 5090 ranks #47 of 98 center channel speakers by sound quality at $799; the Q Acoustics 5020 ranks #105 of 122 bookshelf speakers by sound quality at $1,199.
The case for the Q Acoustics 5090: Dual 4.5-inch C3 Continuous Curved Cone woofers paired with high-performance Point-2-Point internal bracing. The catch: Impedance drops to 3.2 ohms minimum at bass frequencies.
The case for the Q Acoustics 5020: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. The tradeoff: 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.
Buy the Q Acoustics 5090 at $799 if you want a center channel speaker. Buy the Q Acoustics 5020 at $1,199 if you want a bookshelf speaker instead.

Pros: Dual 4.5-inch C3 Continuous Curved Cone woofers paired with high-performance Point-2-Point internal bracing. High 90.5dB sensitivity, low distortion, and deeper bass down to 57Hz.
Cons: Impedance drops to 3.2 ohms minimum at bass frequencies. 2-way horizontal geometry exhibits narrow off-axis sweet spot. Rating estimated based on 5020 and 5040 measurements.

Q Acoustics 5020: $1,199.00 per pair Amazon eBay
Smaller model: the Q Acoustics 5010 (ranked higher, estimated 3.5/5).
Larger models: the Q Acoustics 5040 (rated 4.1/5) and the Q Acoustics 5050 (estimated 4.3/5).
Pros: 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. Measured bass extension of 103Hz (-3dB), with a measured sensitivity of 87.1dB.
Cons: 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.
