Short answer: the Infinity Primus 360. It ranks #40 of 71 floorstanding speakers by sound quality at $650; the Focal Aria Evo X N°2 ranks #58 and costs $2399, so there is not much of a tradeoff to weigh.
What the Focal Aria Evo X N°2 offers: Solid bass with a deliberate mid-bass bump (80-120Hz) that gives extra thump and weight, extending to about 40-50Hz in-room. High sensitivity (measured 88.2dB) makes it easy to drive, and distortion is low throughout the range even at high output - the reviewer found only a minor compression “glare” around 4.5kHz at very high volumes, not a real concern. Directivity components (mid-range and tweeter) transition smoothly rather than abruptly, and the overall soundstage is wide and enveloping. Watch for: Sounds very bright pointed directly at the listener - the tweeter comes in 5-6dB above the midrange with an unusually wide, roughly two-octave dip (1kHz-4kHz) leading into it, giving a laid-back, low-attack character even after toeing out ~20 degrees. Fixing this properly requires real EQ (a mini DSP or similar), not just toe-out or absorption alone; without EQ, expect it to sound bright for stereo listening. A mild dip around 200Hz makes male vocals sound slightly subdued. Narrow vertical directivity (about +/-15 degrees) means you need to stay close to tweeter-axis height. Impedance dips to 3.4 ohms (EPDR 1.4 ohms), so it wants a 4-ohm-capable amplifier, and requires a plinth for floor clearance since it’s bottom-ported.
What the Infinity Primus 360 offers: A three-way tower from 2005 (two 6.5” mid-woofers, a 4” mid-range, and a 0.75” dome tweeter, 8 ohms nominal) that holds up remarkably well by modern measurement standards: on-axis linearity is within about ±2dB, and the listening window stays consistent out to roughly ±30° horizontal and ±10° vertical off the mid-range axis. Horizontal directivity is well controlled out to about ±75° before tonality starts to drift, meaning the reflected sound in a room stays close in character to the direct sound - a speaker that takes EQ well without fighting itself. Harmonic distortion measures low at both 86dB and 96dB, and multitone distortion stays under the reviewer’s 3% threshold. Silky, smooth midrange with a rich lower-midrange/upper-bass character. No mechanical issues or surround degradation found in a 20-year-old pair, and a second unit measured within about 1-1.5dB of the first, suggesting good long-term consistency for the design. Watch for: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average. Bass output drops off fairly quickly below about 50Hz in-room (F3 53Hz, F10 37Hz), so a subwoofer is needed for real low-end extension. Resonances show up around 170Hz, 220Hz, and 350Hz. On-axis, the lower treble can sound a bit bright or sibilant when the speaker is aimed directly at the listener; toeing out about 10-15° (rather than the more extreme 30°) gave the best balance, and some sidewall acoustic absorption further tamed a 4-5kHz peak. Placed close to the rear wall, bass gets boomy - pulling the speakers out about a foot resolves most of it, with roughly 1.5 feet from the wall as a good compromise between bass character and typical room aesthetics. Straying beyond about 25° above or below the mid-range axis introduces audible suckout. No longer in production, so it’s a used/secondhand purchase only.
Buy the Infinity Primus 360. It ranks higher for sound quality than the Focal Aria Evo X N°2 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Focal Aria Evo X N°2. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
