Short answer: the KEF Reference 203 for better sound quality, the Klipsch RP-6000F II for the lower price. The KEF Reference 203 ranks #13 of 71 floorstanding speakers at $5000. The Klipsch RP-6000F II ranks #54 at $1500, $3500 cheaper.
What the KEF Reference 203 offers: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. Distortion is excellent - under 1% harmonic above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good” - a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have. Watch for: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums) - condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening.
What the Klipsch RP-6000F II offers: Highest power handling and clean, well-behaved compression at typical volumes. Precise imaging from the controlled horn directivity. Watch for: 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).
Buy the KEF Reference 203 if sound quality matters more than the price. Buy the Klipsch RP-6000F II if the price matters more than sound quality.
If sound quality matters at all to you, skip the Klipsch RP-6000F II. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
