Short answer: the Klipsch RP-6000F II for cleaner power handling, the Infinity Reference 253 for the lower price. The RP-6000F II ranks #51 of 74 floorstanding speakers at $1,500, though it has worse baffle-step coloration than the RP-5000F II (3-4dB swing vs 2dB) and a sibilance issue. The Reference 253 costs $400 and its roughly ±60 degree beamwidth is smooth, but its predicted in-room response shows treble above 4kHz that is “too hot” and a 2kHz dip.
Buy the Klipsch RP-6000F II. It is rated higher for sound quality and still sold new, while the Infinity Reference 253 is discontinued.

Klipsch RP-6000F II: $1500 per pair Amazon eBay
Pros: Highest power handling and clean, well-behaved compression at typical volumes. Precise imaging from the controlled horn directivity. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 90dB.
Cons: Worse baffle-step coloration than the smaller RP-5000F II (3-4dB swing vs 2dB), plus a sibilance issue the 5000F doesn’t have: a real regression in tonal balance despite the higher price. Bass extension is mixed (less deep at -3dB (67Hz) than the 5000F) and needs a subwoofer regardless. Narrow horizontal dispersion (~50-60 degrees).

Infinity Reference 253: $400 per pair used Discontinued eBay
Pros: Horizontal beamwidth of about ±60 degrees is fairly smooth and well controlled. Really amazing value for the performance. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 86.9dB.
Cons: CEA2034 spinorama and predicted in-room response both show elevated treble above 4kHz (“too hot”), a dip around 2kHz, and bass shelved down relative to the midrange. Vertical directivity requires staying at or below the tweeter axis for accurate tonal balance. Distortion at 96dB SPL/1m is broadly elevated above the reviewer’s audibility threshold across much of the midrange. Minimum impedance dips to 4.2 ohms. Discontinued.
