Short answer: the KEF Blade Two Meta for better sound quality, the Radiant Acoustics Clarity 66 for the lower price. The KEF Blade Two Meta ranks #2 of 71 floorstanding speakers at $28000. The Radiant Acoustics Clarity 66 ranks #5 at $7998, $20002 cheaper.
What the Radiant Acoustics Clarity 66 offers: ASR’s revised Spinorama measurement shows bass reaching 32.2Hz at -3dB and 27.8Hz at -6dB, giving substantial low-end weight without a subwoofer. The response spans 2.3dB from 300Hz to 5kHz, with preference scores of 5.10 standalone and 6.12 with an ideal subwoofer. The review’s exceptionally low bass distortion at ordinary levels complements that extension, while dual 6.5-inch Purifi woofers provide a strong foundation for full-range listening. Watch for: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance. Treble resonances and response irregularities keep it from reference-level neutrality. Spinorama’s modeled EQ improves the scores to 6.09 standalone and 6.99 with an ideal subwoofer, but those are corrected results, not stock performance. Measured sensitivity is 85.9dB at 2.83V/1m with a nominal 4-ohm load; use an amplifier comfortable driving 4 ohms. Distortion rises at very high playback levels.
What the KEF Blade Two Meta offers: True point-source coaxial design (four 6.5in mid-bass drivers flanking a coincident mid/tweeter) with matched ~50 degree horizontal and vertical dispersion, unusual for a multi-driver speaker. Fully rounded, edgeless cabinet eliminates baffle diffraction. Frequency response holds within about 2.5dB across the listening window. Extremely low harmonic and multitone distortion even at 96dB, with under 0.5dB of compression at full output, rivaling the Reference 1 Meta and JBL 4367 in dynamic range. Reviewer described the imaging and soundstage depth as revealing recording details other speakers he tested (PS Audio FR10, MoFi SourcePoint 8, Neumann KH80) masked. Available in any custom finish at no extra charge. Watch for: 2dB dip and slight resonance around 200Hz, also visible in KEF white paper and likely cabinet-related. Bass rolls off fairly quickly below its 31Hz F3. Horizontal dispersion (~50 degrees) is narrower than the reviewer preferred 70-80 degrees; benefits from toeing out 10-20 degrees to open soundstage without losing image focus. Needs a separate power amp, not AVR-friendly.
