Short answer: the JBL Stage 2 250B for better sound quality, the Q Acoustics 3020i for the lower price. The JBL Stage 2 250B ranks #30 of 56 bookshelf speakers at $349.95. The Q Acoustics 3020i ranks #39 at $314.99, $34.96 cheaper.
What the JBL Stage 2 250B offers: Consistent, EQ-able dips in the frequency response mean the tonal issues are at least correctable if you’re willing to use equalization. Watch for: The reviewer was “even less enthusiastic” about this one than its disappointing floorstanding sibling.
On the Q Acoustics 3020i side: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. Set against that: 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.
Buy the JBL Stage 2 250B if sound quality matters more than the price. Buy the Q Acoustics 3020i if the price matters more than sound quality.

JBL Stage 2 250B: $349.95 Amazon
Pros: Consistent, EQ-able dips in the frequency response mean the tonal issues are at least correctable if you’re willing to use equalization. Horizontal dispersion is reasonably wide and controlled (~50-60 degrees). The tweeter itself holds up fine under compression testing - it’s the midwoofer that gives out first.
Cons: The reviewer was “even less enthusiastic” about this one than its disappointing floorstanding sibling. A confusing, hard-to-place tonal signature - a lower-midrange dip creates a recessed, lacking-attack character that’s then partly offset by a rebound around 2-4kHz, so it reads as recessed and forward at different times depending on the material. Treble falls off sharply above 6-7kHz, same issue as the larger 280F. Multitone distortion at 96dB is genuinely poor - well over 3%, reportedly around 10% at some frequencies. Limited bass extension (F3 64Hz, F10 50Hz) means a subwoofer is basically required if used as main speakers. Compression sets in early on the bass/midwoofer at higher output. The reviewer explicitly recommends the similarly-priced Polk Reserve R200/R100 instead for anyone who wants a more linear, EQ-free sound.

Q Acoustics 3020i: $314.99 Amazon
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.”
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.”
