Short answer: the KEF Q3 Meta. It ranks #64 of 100 bookshelf speakers by sound quality at $899.99; the Sonus Faber Lumina II ranks #66 and costs $1600, so there is not much of a tradeoff to weigh.
What the KEF Q3 Meta gets right: Coaxial two-way design (1” vented aluminum dome tweeter with Meta absorber embedded in a 6.5” aluminum cone mid/bass driver) delivering unusually wide dispersion both horizontally and vertically (about ±60° each) -. The catch: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
What the Sonus Faber Lumina II offers: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet - genuinely nice-looking speaker with real brand cachet. Watch for: Not a neutral speaker - has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out.
Buy the KEF Q3 Meta. It ranks higher for sound quality than the Sonus Faber Lumina II and costs less, so there is no real case for the other one.

KEF Q3 Meta: $899.99 Amazon Crutchfield
Pros: Coaxial two-way design (1” vented aluminum dome tweeter with Meta absorber embedded in a 6.5” aluminum cone mid/bass driver) delivering unusually wide dispersion both horizontally and vertically (about ±60° each) - wider than typical KEF models, which usually run closer to ±50° horizontal and ±15-20° vertical for non-coaxial designs. A deliberate ~2dB bump around 120Hz gives a satisfying sense of kick-drum impact, a voicing choice the reviewer personally favors even though it’s not strictly accurate. Extended bass-shelf tuning allows placement close to a rear wall (about 1 foot) without sounding boomy. Good directivity overall means it takes well to EQ correction if desired. Cabinet resonances around 350-370Hz and 600Hz look concerning in impedance measurements, but blind ABX testing (24 trials) after adding damping material couldn’t reliably distinguish the treated cabinet from the untreated one - these particular resonances appear to fall below the threshold of audibility. Sturdier build than previous KEF Q-series models.
Cons: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application. A slight loss of attack and clarity around 1-2kHz was noticeable both subjectively and in measurements. F3 of 52Hz with a fairly quick rolloff below 50Hz means a subwoofer is still recommended for real bass extension, even for moderate-volume home theater use. Sealed configuration (using the included port bungs) pushes the bass rolloff up into the 100Hz+ region - the reviewer recommends leaving it in ported mode instead. Sounds best pointed directly at the listener; toeing it out 30° rolls off the top end without a meaningful soundstage benefit. Compression testing shows real breakdown at 102dB/1m, with the woofer losing excursion control - confirms the practical output ceiling. An unexplained -5dB dip appears in on-axis measurements that the reviewer couldn’t attribute to a specific cause.

Sonus Faber Lumina II: $1600 Crutchfield
Pros: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet - genuinely nice-looking speaker with real brand cachet. Bass extension is competitive for the size, reaching about 50 Hz in-room with mild compression and good distortion figures, so higher output levels and greater listening distances aren’t a problem down to that point. About 20 dB of dynamic range at typical listening levels (73 dB at 4m), which comfortably covers most music without the tonal balance shifting as instruments and vocals peak. Off-axis behavior is consistent - toeing the speakers 20-30 degrees out doesn’t meaningfully change the in-room high-frequency character, so placement flexibility is good once you’ve dialed in the tonal balance.
Cons: Not a neutral speaker - has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out. A slightly nasal quality traced to a resonance around 1 kHz that EQ can address. The reviewer needed to trim treble by about 4 dB on his preamp to get the tonal balance he wanted, meaning most listeners will want equalization available to fully enjoy this speaker. At roughly the same $1,000ish price point, alternatives like the Ascend Acoustics Sierra 1 V2 measure more linear (with a tradeoff in distortion and crossover-region directivity), and the Dynaudio Emit 20 offers deeper bass extension and lower compression at the cost of a more deliberately colored tonal signature.
