Short answer: the Klipsch Forte IV for better sound quality, the Focal Aria Evo X N°2 for the lower price. The Klipsch Forte IV ranks #41 of 68 floorstanding speakers at $5499.98. The Focal Aria Evo X N°2 ranks #58 at $2399, $3100.98 cheaper.
What the Klipsch Forte IV offers: Three-way heritage design: a 1” titanium tweeter and 1.75” compression driver for the midrange mated to a 12” woofer, plus a 15” passive radiator for extra bass reinforcement. Genuinely resonance-free cabinet, a clear improvement over the notably boomy, resonant Heresy 4 in the same lineup. Surprisingly wide, expansive soundstage that beat both the Heresy 4 and a KEF LS50 Wireless 2 in direct comparison - images occasionally appeared several feet outside the physical speaker location. Deeper bass extension than the Heresy 4 (F3 of 82Hz, about 10Hz lower). Distortion measures well below 1% at 86dB and stays mostly within 1% even at 96dB. Comes as a factory-matched serial-numbered pair, backed by an unusually generous 10-year warranty. Mostly above 4 ohms impedance, so it’s compatible with AVRs, solid-state, or tube amplifiers. More neutral overall than other Klipsch models the reviewer has tested, making it a reasonable pick for listeners who already like the “Klipsch sound” but want something more balanced. Watch for: Contrary to the classic Klipsch reputation for being forward and bright, this model is actually somewhat recessed in the 1.5-4kHz “presence” region, which can make some tracks sound dull or lacking in detail. A peak around 6kHz reads as sibilant and “painful” when seated exactly on the tweeter axis; sitting a bit above that axis reduces it somewhat. Klipsch’s marketed 99dB sensitivity figure is an in-room rating that assumes 3-6dB of boundary gain - anechoic sensitivity measures closer to 94dB, which the manufacturer does disclose but can still mislead buyers comparing spec sheets. Radiation width isn’t consistent across all frequencies - a noticeable notch around 2-3kHz interrupts otherwise wide dispersion, which can cause a fundamental tone and its harmonics to image in slightly different places in the soundstage. Uses shallow low-pass crossover slopes (despite Klipsch’s steep-crossover marketing, which applies only to the high-pass side), likely contributing to some of the measured dips and possible cone-breakup artifacts. Some compression shows up around the midrange crossover point at very high output (102dB), though likely only audible at extreme volumes. At around $5,000/pair, a significant investment, and still needs a subwoofer for material extending below about 50Hz.
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.
Buy the Klipsch Forte IV if sound quality matters more than the price. Buy the Focal Aria Evo X N°2 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Focal Aria Evo X N°2. It ranks near the bottom of the 68 floorstanding speakers, so look higher up the list instead.
