Short answer: the Revel F328Be for better sound quality, the KEF Q11 Meta for the lower price. The Revel F328Be ranks #9 of 188 floorstanding speakers, rated 4.7/5, at $19,359.90. The KEF Q11 Meta ranks #103, rated 4.0/5, at $2,499.98, $16,859.92 cheaper.
The KEF Q11 Meta is the deeper-bass pick. Three-way tower design with a coaxial layout: a 3/4” aluminum dome tweeter (with KEF’s Metamaterial Absorption Technology behind it) mounted at the center of a 4” mid-range, plus three 6.5” bass drivers. Its bass reaches about 60Hz before falling 3dB, against 74Hz for the Revel F328Be. The tradeoff: Genuinely dark-sounding on raw on-axis measurement, and needs a typical room with sidewall reflections (within about 6 feet/2 meters) to sound properly neutral: in a large room with little sidewall interaction, it may sound too dull for some listeners.
The Revel F328Be is the better-sounding pick. CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. The catch: Vertical directivity is asymmetric: the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower.

KEF Q11 Meta: $2,499.98 per pair Amazon eBay
Same family: the KEF Q1 Meta (smallest bookshelf, rated 3.6/5), the KEF Q4 Meta (bookshelf, estimated 3.4/5), the KEF Q3 Meta (bookshelf, rated 3.4/5), the KEF Q Concerto Meta (largest bookshelf, rated 4.6/5), the KEF Q7 Meta (smaller floorstanding, ranked lower, estimated 3.5/5) and the KEF Q6 Meta (center, rated 3.9/5).
Pros: Three-way tower design with a coaxial layout: a 3/4” aluminum dome tweeter (with KEF’s Metamaterial Absorption Technology behind it) mounted at the center of a 4” mid-range, plus three 6.5” bass drivers. Extremely linear estimated in-room response when placed correctly, thanks to a deliberately declining on-axis response paired with well-controlled directivity: a technically sound design philosophy, even though it reads as “dark” in raw anechoic on-axis measurements. In-room bass extension to about 40-50Hz when placed near a wall, thanks to extended bass-shelf tuning. Sounds excellent whether pointed directly at the listener or toed out a full 30° parallel to the back wall: unusually flexible placement. More vertical listening leeway than standard non-coaxial two-way designs, thanks to the coincident tweeter/midrange. Distortion looks good at both 86dB and 96dB, and multitone distortion holds up well too. Comes with a plinth/outrigger kit for stability given its floorstanding height (about 43-44”). Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 88.6dB.
Cons: Genuinely dark-sounding on raw on-axis measurement, and needs a typical room with sidewall reflections (within about 6 feet/2 meters) to sound properly neutral: in a large room with little sidewall interaction, it may sound too dull for some listeners. Must be placed close to a rear wall (about 1 foot) to get proper bass: pulling it out to the “standard” 3-foot audiophile recommendation causes bass output to drop off noticeably. Horizontal radiation of about ±50° is narrower than the reviewer’s preferred ±60°, giving a slightly less enveloping soundstage than some rivals. Notably darker than sibling KEF models in the same product family: measures 2-5dB less top-end energy than the R3 Meta and a few dB less than the Q Concerto Meta. Minor lingering resonances appear in burst decay measurements between 500Hz-1kHz. The tweeter shows some strain at very high output volumes, a limitation the reviewer notes is common even among more budget-friendly speakers generally.

Revel F328Be: $19,359.90 per pair Crutchfield eBay
Same family: the Revel M126Be (bookshelf, rated 4.3/5), the Revel F226Be (smaller floorstanding, ranked lower, rated 4.6/5), the Revel F228Be (smaller floorstanding, ranked lower, rated 4.5/5) and the Revel C426Be (center, rated 4/5).
Pros: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Predicted in-room response is extremely accurate, with a smooth ~5dB downward slope from bass to treble that suits typical rooms without correction. Early reflections sum very nicely with the direct sound. Horizontal beamwidth of about ±70 degrees is wide and quite smooth. At 96dB SPL/1m distortion stays easily below the reviewer’s audibility threshold across nearly the whole range. Measured bass extension of 74Hz (-3dB), with a measured sensitivity of 91dB.
Cons: Vertical directivity is asymmetric: the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower. Impedance dips to a minimum of 3 ohms with an additional resonance-driven phase swing, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).
