Short answer: the KEF LS50 Meta for better sound quality, the KEF Q1 Meta for the lower price. The KEF LS50 Meta ranks #4 of 168 bookshelf speakers, rated 4.5/5, at $1,599.99. The KEF Q1 Meta ranks #64, rated 3.6/5, at $399.99, $1,200 cheaper.
The KEF LS50 Meta is the better-sounding option. Uni-Q concentric driver mounts a 1” vented aluminum dome tweeter at the center of a 5.25” aluminum cone woofer, rated 79Hz-20kHz+. The catch: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
Why pick the KEF Q1 Meta: 12th generation Uni-Q coaxial driver places the 1” vented aluminium dome tweeter at the centre of the 5.25” aluminium woofer, with KEF’s Metamaterial Absorption Technology behind the tweeter. Watch for: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies.
Buy the KEF LS50 Meta when sound quality outweighs the price for you, and the KEF Q1 Meta when the price outweighs sound quality instead.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

The Two Speakers In Full
KEF LS50 Meta: $1,599.99 per pair Amazon Crutchfield eBay
Older model: the KEF LS50 (ranked lower, rated 3.9/5). See every KEF LS50 generation.
Pros: Uni-Q concentric driver mounts a 1” vented aluminum dome tweeter at the center of a 5.25” aluminum cone woofer, rated 79Hz-20kHz+. Speaker-to-speaker matching measured tight at roughly 0.5dB deviation between the pair tested, versus 2-3dB seen on some other speakers: likely why imaging stayed so precise. Imaging stays tight and focused even toed out, unlike most coincident designs where toe-out typically diffuses the image, giving more of an oval-shaped soundstage than a hard rectangular boundary. Horizontal and vertical directivity both hold to about ±50° at the -6dB point, so tonality stays consistent across roughly a 100° listening cone. The extended bass shelf is deliberately tuned for near-wall/boundary placement rather than the usual “pull it 3 feet into the room” advice, playing lower without excess boominess when placed close to a wall. At its frequent sale price, well below list, called a no-brainer for a compact stand-mount speaker. Independent ASR Klippel measurements corroborate this: very good directivity with the on- and off-axis curves tracking closely, and a predicted in-room response the reviewer called “very close to ideal.”. Measured bass extension of 68Hz (-3dB), with a measured sensitivity of 83dB.
Cons: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass. A 2-3dB scoop around 2-4kHz shows up in both the listening window and sound power measurements, matching a subjectively noticed lack of attack and vocal clarity that the reviewer wanted to correct with about 2dB of EQ. An on-axis diffraction dip around 8kHz smooths out with about 15° of toe-out (typical for concentric designs, but still present at 0°). Distortion is elevated at low frequencies since the single 5.25” cone shares surface area with the tweeter housing, reducing effective radiating area; multitone distortion crosses the 3% threshold at 96dB/1m, making roughly 88dB or below the safer output ceiling. Moderate sensitivity (~83dB average) needed 2-3dB more amplifier gain than typical in testing. Adding a subwoofer at an 80Hz crossover only helps lower-midrange distortion, not the elevated distortion in the 1-2kHz and above-5kHz regions. ASR’s own Klippel testing found the same pattern in starker terms: THD is very good at 86dB SPL/1m but climbs past 100% in the bass at 96dB SPL/1m, confirming this is not a near-field speaker for high-output bass-heavy material. Cumulative spectral decay (waterfall) also shows a couple of resonances lingering in the 1-2kHz region.

KEF Q1 Meta: $399.99 per pair Amazon eBay
Older models: the KEF Q150 (ranked higher, rated 3.7/5) and the KEF Q100 (ranked lower, rated 2.4/5). See every KEF Q Series generation.
Same family: the KEF Q4 Meta (larger bookshelf, ranked lower, estimated 3.4/5), the KEF Q3 Meta (larger bookshelf, rated 3.4/5), the KEF Q Concerto Meta (larger bookshelf, rated 4.6/5), the KEF Q7 Meta (smaller floorstanding, estimated 3.5/5), the KEF Q11 Meta (larger floorstanding, rated 4/5), the KEF Q6 Meta (center, rated 3.9/5) and the KEF Q8 Meta (surround, rated 3.4/5).
Pros: 12th generation Uni-Q coaxial driver places the 1” vented aluminium dome tweeter at the centre of the 5.25” aluminium woofer, with KEF’s Metamaterial Absorption Technology behind the tweeter. KEF’s own Spinorama measurements, published on spinorama.org, hold the 300Hz to 5kHz response within 2.3dB with a flat on-axis trend, so the tonal balance is even. Measured bass reaches 65Hz (-3dB) and about 43Hz (-10dB), respectable for a compact bookshelf. Same cabinet size as the KEF Q150 it replaces. Measured bass extension of 65.1Hz (-3dB).
Cons: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies. Sound power directivity is less even than the best in this class (3.16dB index deviation), so off-axis listeners and room reflections shift the balance more. Minimum impedance of 3.2 ohms is a harder load than the KEF Q150’s, and rated maximum output is a modest 108dB, so plan on a subwoofer for loud listening.
