Short answer: the Polk Audio XT15. It ranks #52 of 160 bookshelf speakers by sound quality (rated 3.7/5) at $149 and is still sold new; the Q Acoustics 3020i ranks #132 (rated 2.4/5) and is discontinued, so it is only an option used. The Q Acoustics 3020i’s replacement, the Q Acoustics 3020c, is rated 2.6/5.
What the Q Acoustics 3020i does well: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. The catch: On-axis response shows a rising upper-frequency trend and a dip in the 2-4kHz crossover region alongside two resonance-related dips; a significant resonance appears at 366Hz in the waterfall plot.
The Polk Audio XT15 is the more accurate pick. Very low $149/pair entry price for a Hi-Res Audio Certified 2-way design that’s Dolby Atmos and DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs so it drops into almost any AVR without matching concerns. Its measured preference score, a predictor of how neutral it sounds, is 4.56 against 3.86 for the Q Acoustics 3020i. The catch: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB).
Buy the Polk Audio XT15. It is rated higher for sound quality; the Q Acoustics 3020i is no longer sold new.

Q Acoustics 3020i: $314.99 per pair Discontinued eBay
Newer model: the Q Acoustics 3020c, ranked higher, estimated 2.6/5.
Same family: the Q Acoustics 3030i (larger bookshelf, rated 4/5).
Pros: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. Vertical directivity is good enough that the tweeter doesn’t need to be exactly at ear level. With EQ correction, especially high-frequency shelving and a sub-40Hz high-pass filter, Amir found performance “improves substantially.”. Measured bass extension of 82.0Hz (-3dB).
Cons: On-axis response shows a rising upper-frequency trend and a dip in the 2-4kHz crossover region alongside two resonance-related dips; a significant resonance appears at 366Hz in the waterfall plot. Horizontal directivity is narrow and uneven due to a woofer/tweeter beamwidth mismatch. Amir cautions the speaker is “merely a distortion generator” if played too low, and its low impedance demands a quality amplifier. Without EQ, Amir “can’t recommend the Q Acoustics 3020i.”. Discontinued; Q Acoustics now sells the 3030i and 3010c in its place.

Polk Audio XT15: $149.00 per pair Amazon B&H Photo Video Crutchfield eBay
Same family: the Polk Monitor XT20 (larger bookshelf, rated 3.4/5), the Polk Audio XT60 (smaller floorstanding, rated 3.5/5), the Polk Audio XT70 (larger floorstanding, rated 3.6/5), the Polk Audio XT30 (smaller center, rated 3.6/5), the Polk Audio XT35 (larger center, rated 4.1/5), the Polk Audio Monitor XT10 (smaller subwoofer, estimated 3.1/5) and the Polk Audio Monitor XT12 (larger subwoofer, estimated 3.3/5).
Pros: Very low $149/pair entry price for a Hi-Res Audio Certified 2-way design that’s Dolby Atmos and DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs so it drops into almost any AVR without matching concerns. Off axis sound tracks the on axis response reasonably consistently for the price. Measured bass extension of 77.6Hz (-3dB).
Cons: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB). On-axis response is relatively uneven, with an average deviation of about 0.45dB, and its listening window is less smooth than pricier speakers. Modest 86dB sensitivity wants a reasonably powered amp channel. The 5.25” bi-laminate paper woofer is Polk’s entry-tier driver, not the polypropylene/Turbine cones used in its pricier Signature Elite/Reserve lines.
