Short answer: the Paradigm Persona 3F on measured sound quality, the Klipsch Forte IV on price. The Paradigm Persona 3F ranks #103 of 226 floorstanding speakers, rated 4.2/5, at $11,999.98. The Klipsch Forte IV ranks #122, rated 4.0/5, at $5,499.98, $6,500 cheaper.
The case for the Paradigm Persona 3F: A three-way tower with a beryllium tweeter, a 7” Truextent beryllium midrange/bass driver and two 7” X-PAL woofers. The tradeoff: Paradigm’s data does not cover bass reliably, so it has no preference score; the rating is estimated from that data.
What the Klipsch Forte IV does well: 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. 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.
Buy the Paradigm Persona 3F when sound quality outweighs the price for you, and the Klipsch Forte IV when the price outweighs sound quality instead.
Worth knowing: the Paradigm Persona 3F has not been measured yet. Its rating is estimated from related models, with a likely range of 3.8 to 4.6, so treat this verdict as provisional.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

Paradigm Persona 3F: $11,999.98 per pair Estimated Paradigm eBay
Same family: the Paradigm Persona B (bookshelf, estimated 4.1/5), the Paradigm Persona 5F (larger floorstanding, ranked higher, estimated 4.3/5), the Paradigm Persona 7F (larger floorstanding, ranked higher, estimated 4.4/5), the Paradigm Persona 9H (larger floorstanding, ranked higher, estimated 4.4/5), the Paradigm Persona C (center, estimated 4.2/5) and the Paradigm Persona SUB (subwoofer, estimated 4.2/5).
Pros: A three-way tower with a beryllium tweeter, a 7” Truextent beryllium midrange/bass driver and two 7” X-PAL woofers. Paradigm rates it within ±2dB from 48Hz to 45kHz, and its own measurements show a fairly even listening window. Sensitivity is 89dB.
Cons: Paradigm’s data does not cover bass reliably, so it has no preference score; the rating is estimated from that data. It weighs 34kg each.

Klipsch Forte IV: $5,499.98 per pair Amazon Crutchfield eBay
Same family: the Klipsch Heresy IV (smaller floorstanding, ranked lower, rated 2.3/5), the Klipsch Cornwall IV (larger floorstanding, ranked lower, estimated 2.8/5), the Klipsch La Scala AL6 (larger floorstanding, ranked lower, estimated 2.8/5) and the Klipsch Klipschorn AK7 (larger floorstanding, ranked lower, estimated 3/5).
Pros: 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 Klipsch Heresy IV in the same lineup. Surprisingly wide, expansive soundstage that beat both the Klipsch Heresy IV and a KEF LS50 Wireless 2 in direct comparison: images occasionally appeared several feet outside the physical speaker location. Deeper bass extension than the Klipsch Heresy IV (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. Measured bass extension of 82Hz (-3dB), with a measured sensitivity of 93.8dB.
Cons: 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 $5500/pair, a significant investment, and still needs a subwoofer for material extending below about 50Hz.
