Short answer: the Revel F228Be. It ranks #28 of 188 floorstanding speakers by sound quality, rated 4.5/5, at $11,000. The Klipsch Heresy IV ranks #184, rated 2.3/5, at $3,599.98, $7,400.02 cheaper, which does not close the gap in sound quality.
The Revel F228Be is the more accurate, deeper-bass option. CEA2034 spinorama shows an essentially flat on-axis response with very nice directivity. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 2.27 for the Klipsch Heresy IV. Its bass reaches about 61Hz before falling 3dB, against 77Hz for the Klipsch Heresy IV. The tradeoff: Minimum impedance dips to 3.4 ohms with a secondary rise around 2kHz, calling for an amplifier comfortable with a demanding load.
The case for the Klipsch Heresy IV: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement (well below Klipsch’s 99dB in-room claim, but still excellent) and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. The catch: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction.
Buy the Revel F228Be. It is rated higher for sound quality, and the $7,400.02 you would save on the Klipsch Heresy IV does not close the gap.

Revel F228Be: $11,000 per pair Crutchfield eBay
Older model: the Revel F208 (ranked higher, rated 4.5/5).
Same family: the Revel M126Be (bookshelf, rated 4.3/5), the Revel F226Be (smaller floorstanding, ranked higher, rated 4.6/5), the Revel F328Be (larger floorstanding, ranked higher, rated 4.7/5) and the Revel C426Be (center, rated 4/5).
Pros: CEA2034 spinorama shows an essentially flat on-axis response with very nice directivity. Predicted in-room response is nearly perfect, with a smooth slope down from bass to treble. Horizontal beamwidth of about ±70 degrees is wide and holds up well until narrowing above 8kHz. Vertical directivity offers more degrees of listening-height freedom than a typical bookshelf design, a benefit of this tower’s driver layout. Distortion is extremely low across the full audio range at 86dB SPL/1m and stays comfortable even at 96dB SPL/1m. Near-field measurements of the individual drivers show nice, well-integrated crossover behavior with only low-level resonances. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 89.3dB.
Cons: Minimum impedance dips to 3.4 ohms with a secondary rise around 2kHz, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).

Klipsch Heresy IV: $3,599.98 per pair Amazon Crutchfield eBay
Same family: the Klipsch Forte IV (larger floorstanding, ranked higher, rated 4/5), the Klipsch Cornwall IV (larger floorstanding, ranked higher, estimated 2.8/5), the Klipsch La Scala AL6 (larger floorstanding, ranked higher, estimated 2.8/5) and the Klipsch Klipschorn AK7 (larger floorstanding, ranked higher, estimated 3/5).
Pros: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement (well below Klipsch’s 99dB in-room claim, but still excellent) and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. The compact, furniture-grade Heritage cabinet is easier to place than most high-efficiency designs, and dynamics at moderate levels can sound lively. A stable four-ohm-capable amplifier can produce substantial SPL with relatively little voltage. Measured bass extension of 77Hz (-3dB), with a measured sensitivity of 94.5dB.
Cons: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction. The impedance dips to about 4 ohms, reducing the practical amplifier advantage implied by its sensitivity. Pronounced directivity mismatch at the driver transitions, impedance/response resonances and elevated distortion spikes around the crossover remain audible concerns that EQ cannot fully solve. At 102dB Erin measured roughly 1.5dB midband compression; at 96dB distortion rises around crossover. Performance is difficult to justify at the price, and Erin explicitly did not recommend it.
