Short answer: the Radiant Acoustics Clarity 66 on measured sound quality, the Revel F226Be on price. The Radiant Acoustics Clarity 66 ranks #5 of 71 floorstanding speakers at $7998. The Revel F226Be ranks #11 at $7700, $298 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 Revel F226Be offers: Compact three-way tower with a beryllium dome tweeter in an acoustic lens waveguide, a dedicated 5.25” mid-range, and dual 6.5” woofers (not a coaxial layout) - all Deep Ceramic Composite aluminum cones engineered specifically to avoid breakup outside their crossover bands, and it measures that way: neither the woofers nor the mid-range show breakup spikes even well outside their intended pass bands, and even the front port measures unusually clean (only a mild ~3dB bump around 150Hz, well controlled versus the resonances the reviewer typically sees from ports). On-axis frequency response holds within about ±1.5dB above roughly 65Hz - excellent linearity - and off-axis behavior tracks it closely, with only mild, subdued peaking around 4-6kHz that doesn’t show up as real resonance in the spinorama data. Average sensitivity around 90dB (2.83V/1m), notably higher than some competing three-way designs and most bookshelf speakers, translating directly into better dynamic range at both low and high listening levels - one reviewer specifically praised its ability to deliver full transient impact (snare hits, kick drum) even at quiet, conversational volumes rather than needing to be cranked up to feel dynamic. Wide, consistent horizontal radiation of about ±60-70° at the -6dB point, landing right in the reviewer’s preferred range for an enveloping soundstage without excess diffusion, and exceptionally wide vertical dispersion - roughly ±80° up to 10kHz and still ±70° above that, which one reviewer called the widest vertical radiation pattern he had measured to date. Distortion stays under 3% even at 104dB SPL, and in real-world testing up to 105dB from 12-14 feet away, full-range with no crossover, the reviewer heard no audible mechanical noise, port chuffing, or compression at all. Flat enough on- and off-axis response that toeing the speaker 10-15° away from the listener preserves the same tonal balance rather than changing it, and the wide, well-controlled directivity lets sidewall reflections reinforce rather than smear the soundstage. Watch for: Minimum impedance dips to about 3.7-4 ohms below roughly 500Hz despite the 8-ohm nominal rating, so it wants a genuine 4-ohm-capable two-channel amplifier; budget AVRs rated only for 6 or 8 ohms may struggle. F3 of 56Hz and F10 of 36Hz mean it doesn’t extend nearly as low as some three-way rivals with larger woofers - a dedicated subwoofer (10-12”, or 15” for content below 30Hz) is recommended for home theater or bass-heavy music, even though the speaker itself can play surprisingly loud without one. Vertical directivity tolerance is tighter in the crossover handoff region than a true coaxial design would offer, since the tweeter, midrange, and woofers are physically separated - a mild directivity bump appears around 2-2.5kHz that’s typical of non-coaxial multi-way speakers, though not audibly problematic within about ±10° vertically. On-axis, the top end reads as a bit bright according to one reviewer’s subjective impression, generally benefiting from some toe-out. High-gloss cabinet finish can create distracting reflections if used behind a projector screen in a home theater setup. Front-ported, so it can technically sit close to a wall, but doing so makes the bass boomier.
