Short answer: the Dynaudio Contour 20i. It ranks #92 of 203 bookshelf speakers by sound quality (rated 3.9/5) at $5,750 and is still sold new; the Focal Aria 906 ranks #150 (rated 3.3/5) and is discontinued, so it is only an option used. The Focal Aria 906’s replacement, the Focal Aria Evo X N°1, is rated 3.5/5.
The case for the Focal Aria 906: CEA2034 spinorama shows very flat bass response, with the reviewer rating overall performance “good.” Watch for: 3dB dip around 2.8kHz.
The Dynaudio Contour 20i is the better-sounding, deeper-bass choice. Two-way design with a 1.125” Esotar2i silk dome tweeter and a 7” magnesium silicate polymer woofer in a vented enclosure. Its bass reaches about 56Hz before falling 3dB, against 63Hz for the Focal Aria 906. The tradeoff: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment.
Buy the Dynaudio Contour 20i. It is rated higher for sound quality; the Focal Aria 906 is no longer sold new.

Focal Aria 906: $2,199.00 per pair used Discontinued Amazon eBay
Newer model: the Focal Aria Evo X N°1, ranked higher, estimated 3.5/5.
Pros: CEA2034 spinorama shows very flat bass response, with the reviewer rating overall performance “good.” Predicted in-room response is almost perfect prior to 1kHz. Horizontal dispersion of about ±60 degrees is good and stays even out to about -12dB before getting erratic. Woofer distortion is quite low at 86dB SPL/1m. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: 3dB dip around 2.8kHz. Some resonance around 800Hz, small directivity error around 7kHz. A dip in the upper midrange also shows up in the predicted in-room response. Distortion becomes problematic at 96dB SPL/1m, with a notable peak around 1.3-1.5kHz alongside broader midrange elevation. Discontinued.

Dynaudio Contour 20i: $5750 per pair Safe and Sound HQ eBay
Pros: Two-way design with a 1.125” Esotar2i silk dome tweeter and a 7” magnesium silicate polymer woofer in a vented enclosure. A shallow bass rolloff profile lets it sit closer to a wall (about 1-2 feet worked best in testing) without becoming boomy, and makes subwoofer integration comparatively easy. Very wide horizontal radiation (about ±70° through the midrange) gives an enveloping, spacious sound in a suitably sized room. On-axis response holds within about ±3dB overall and ±1.5dB through the midrange. Attractive build quality with a distinctive metal front baffle and gloss finish options. Long-term compression stays good up to 96dB, and short-term compression is within about 0.5dB at that same level. Measured bass extension of 56Hz (-3dB).
Cons: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment. A roughly 2dB lift in the lower treble combined with wide dispersion means more energy reflecting off sidewalls than some listeners will prefer. Relatively low sensitivity (about 82.5dB measured). Unusually sensitive to amplifier output impedance: high-output-impedance amps like tube or SET designs introduce up to a 2dB dip in the midrange, making the sound more mellow rather than “warmer,” the opposite of what many tube-amp buyers expect. Elevated harmonic and multitone distortion around 700Hz, which the reviewer attributes to typical cone-edge/surround behavior common across many driver brands, though it stands out on the measurement graphs. An upper-midrange dip around 2kHz can reduce attack and clarity on vocals and brass instruments. Vertical listening window is fairly narrow (roughly -20° to +30°): moving outside that range causes a noticeable tonal shift, unlike coaxial designs that tolerate more vertical movement.
