Short answer: the Focal Chora 816 for better sound quality, the Infinity Primus 360 for the lower price. The Focal Chora 816 ranks #14 of 71 floorstanding speakers at $900. The Infinity Primus 360 ranks #40 at $650, $250 cheaper.
What the Focal Chora 816 offers: CEA2034 spinorama shows a generally even on-axis response with nice bass extension and high sensitivity. Predicted in-room response is very good aside from a peak around 8kHz. Horizontal beamwidth of about ±60 degrees is typical and fairly controlled. Distortion is very low at 86dB SPL/1m and still usable at 96dB SPL/1m. Watch for: Some messiness appears between 500Hz-2kHz on-axis, including a dip around 550Hz. Vertical directivity narrows a little, so listening height matters more than with a coincident design. Cumulative spectral decay (waterfall) shows a fair bit of resonances lingering across the midrange. Distortion rises substantially in the 1-2kHz region at 96dB SPL/1m. Minimum impedance dips to about 3.9 ohms.
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 Focal Chora 816 if sound quality matters more than the price. Buy the Infinity Primus 360 if the price matters more than sound quality.
