Short answer: the Klipsch RP-500M II. It ranks #27 of 160 bookshelf speakers by sound quality, rated 4.0/5, at $389.99; the Q Acoustics 5020 ranks #140, rated 2.2/5, and costs $1,199, so there is little reason to consider the other one.
The Klipsch RP-500M II is the more accurate, deeper-bass choice. Major mid-range clarity improvement over the original RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. Its measured preference score, a predictor of how neutral it sounds, is 5.22 against 3.63 for the Q Acoustics 5020. Its bass reaches about 67Hz before falling 3dB, against 103Hz for the Q Acoustics 5020. The tradeoff: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB, in line with typical bookshelf speakers this size, so it isn’t the outlier in efficiency the spec sheet implies.
What the Q Acoustics 5020 does well: 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 Klipsch RP-500M II. It is rated higher for sound quality than the Q Acoustics 5020 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Klipsch RP-500M II: $389.99 per pair Amazon eBay
Older model: the Klipsch RP-500M (ranked lower, rated 3.4/5).
Same family: the Klipsch RP-600M II (larger bookshelf, rated 3.7/5), the Klipsch RP-5000F II (smallest floorstanding, rated 4/5), the Klipsch RP-6000F II (floorstanding, rated 3.9/5), the Klipsch RP-8000F II (largest floorstanding, rated 3.9/5), the Klipsch RP-404C II (smallest center, rated 3.7/5), the Klipsch RP-500C II (center, rated 3.9/5) and the Klipsch RP-504C II (largest center, rated 3.8/5).
Pros: Major mid-range clarity improvement over the original RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. More neutral and linear overall than its sibling RP-600M II, which carries about 2-3dB more high-frequency energy and a touch more bass but less overall balance. Very precise soundstage imaging and instrument placement. Distortion through the midrange is cleaner than the previous generation. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB, in line with typical bookshelf speakers this size, so it isn’t the outlier in efficiency the spec sheet implies. Horizontal dispersion of about ±40-50° is narrower and more directive than the reviewer’s preference for a wider, more enveloping soundstage. Toeing the speaker out to widen the soundstage or soften on-axis brightness comes at some cost to imaging precision. Slightly less clean in the tweeter region than the midrange, likely tied to crossover placement, though not considered a dealbreaker. Low-frequency output is limited: measured around 95dB at 4 meters for the pair before the woofers started to unload, so a subwoofer is recommended for anyone wanting real bass rather than stepping up to a larger model.

Q Acoustics 5020: $1,199.00 per pair Amazon eBay
Same family: the Q Acoustics 5010 (smaller bookshelf, ranked higher, estimated 3.5/5), the Q Acoustics 5040 (smaller floorstanding, rated 4.1/5), the Q Acoustics 5050 (larger floorstanding, estimated 4.3/5) and the Q Acoustics 5090 (center, estimated 3.7/5).
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.
