KEF LS50 Meta

Sources split, but lopsidedly. The labs and most reviewers hear a neutral, even balance — slightly warm, if anything, and smoother than the original LS50. A minority of owners and auditioners hear the same speaker as lifeless, thin or tinny; they include an owner coming from the original LS50 on a McIntosh integrated, a dealer audition on Anthem electronics, and a desk setup near a wall in a small room.

Sources split, and the split roughly follows placement and expectations. The larger camp — ASR, Erin, Stereophile, TNW and several owners — calls it light for anything beyond moderate levels and recommends a subwoofer. The smaller camp calls it full and generous for a 5.25-inch speaker: SoundStage on 24-inch stands with a 60 W Hegel H95 in a living room, Hi-Fi News on 24-inch stands, What Hi-Fi about 50 cm into the room, and an owner with a Primare i35 near the wall of a 15 m² room. Two owners report thin or boomy bass in quite different spots: one on a desk near the wall of a 13×13 ft room, one about a foot and a half from the walls.

Broadly praised for vocals: Stereophile found vocal images 'especially palpable', Klaus Eulenbach titles his review after female vocals, What Hi-Fi calls the midrange detailed and clear, and SoundStage heard nothing stray far from neutral. The dissent is narrow. Erin hears slight upper-midrange issues that take some edge off attack, TNW links a 2.5 kHz dip to a slightly laid-back sound, and one owner missed midrange clarity.

“IMHO, the forte of the LS50 is definitely with female voices, which make them a great choice for Jazz vocalists.”

Klaus Eulenbach (Chord Anni, stands, 2.5–3 m)

“vocal images were especially palpable with these speakers.”

John Atkinson, Stereophile

“missing the clarity on the midrange”

Sources split three ways, with a clear majority. Most hear the treble as clean, smooth and free of sibilance — cleaner than the original LS50 — and a couple hear it as gently rolled off, which they don't mind. A minority hear grain or harshness: an AVForums owner on a 50 W Denon, an auditioner in a dealer's treated room on Anthem electronics, and an owner who fixed harshness in his room by toeing the speakers out. One original-LS50 owner heard the opposite: less top end, and duller.

A near-consensus strength. SoundStage, Stereophile, Hi-Fi News, What Hi-Fi, Klaus Eulenbach and Erin all describe a stage that detaches from the cabinets, with an owner finding it grew once the speakers were about three feet from the back and side walls. Dissent comes from an original-LS50 owner who heard a much smaller stage and an AVForums owner who preferred his Triangles' width. TNW would trade some of it for more width.

“the sound was so free of the speaker cabinets that the only clues that the speakers were there were visual.”

Doug Schneider, SoundStage! Hi-Fi (Purifi Eigentakt, 8 ft listening distance)

“The LS50 Meta generate an expansive and tightly focused soundstage where the instruments are layered convincingly.”

What Hi-Fi?

“I also think the soundstage sounds MUCH smaller with the new speakers.”

age_of_raava, r/audiophile

The most agreed-on strength. The coaxial driver gives a sharply focused phantom centre and precise placement, and SoundStage rated it ahead of a $16,999 Focal on that point. One AVForums owner heard his horn-tweeter Triangles image better.

“But for precision of aural images, the LS50 Metas leapt ahead with hyper-focused images that few speakers can match.”

Doug Schneider, SoundStage! Hi-Fi

“the Metas nicely balance soundstage width with spectacular imaging precision.”

Napier Lopez, TNW

“What struck me first was the incredible stereo image that has a very precise center.”

Klaus Eulenbach

Mostly praised, especially for low-level detail at quiet volumes (Stereophile, SoundStage, What Hi-Fi, TNW). The dissent: Erin hears a slight lack of attack or detail from the upper midrange, Klaus Eulenbach finds it less detailed but more forgiving than his HEDD Type 07 monitors, and one owner missed midrange clarity.

“I was continually surprised by how recordings I thought I knew well were presented with detail that I had not fully appreciated with the earlier LS50s.”

John Atkinson, Stereophile (Parasound Halo JC 1+ monoblocks)

“the LS50 Meta seemed to be exceptionally good at revealing details at low volumes.”

Napier Lopez, TNW

“However, there are some limitations, such as a lack of low bass and slight issues in the upper midrange causing a lack of “attack” or “detail”.”

Erin's Audio Corner

Good for the size at moderate levels, but limited when pushed — and how much that matters depends on distance, room and music. ASR heard low bass notes change tone and then crackle, and Erin found distortion audible at high volume. SoundStage found it clean when cranked but missing the last bit of effortlessness, and one owner on a Denon AVR found it subdued next to KEF's cheaper Q350. Hi-Fi News pushed it past its own comfort level and was impressed, What Hi-Fi says it rarely sounds stressed short of high volume, and TNW heard better dynamics than it expected from a 5-inch speaker.

“The driver is simply too small/lacks the excursion for high dynamic range.”

amirm, Audio Science Review

“the LS50 Metas’ sound remained strikingly clean, but lacked the last bit of effortlessness that bigger speakers can convey.”

Doug Schneider, SoundStage! Hi-Fi

“These are refined and composed performers that rarely sound stressed unless volume levels are high.”

What Hi-Fi?

Placement guidance more than disagreement, and the sources name their setups. What Hi-Fi says keep them out of bookshelves and off the wall — about 50 cm into the room, away from side walls. Stereophile's pair, well out in a large room, would have gained bass closer to the wall. An owner in a 200 sq ft room puts them a few inches from the front wall for a 'free boost', while another found a boomy result even 18 inches out. On aim, ASR says point them at you because directivity is a little narrow, while Erin finds the best balance about 15° off-axis and one owner cured harshness by toeing them out. The coaxial driver makes listening height uncritical, and TNW notes it can be laid on its side as a centre speaker.

“They won’t sulk if you do, but they will sound a lot better if placed around 50cm into a room and well away from the sidewalls.”

What Hi-Fi?

“So I suggest pointing the speaker at you.”

amirm, Audio Science Review

“Best sound balance achieved at about 15° off-axis”

Erin's Audio Corner

The named debate, and it is lopsided. Most sources, measurement and editorial alike, say it wants a capable amplifier that is happy into 4 ohms: ASR, Stereophile, Hi-Fi News ('This will not be happy with a 30W/ch integrated'), What Hi-Fi ('a bit of grunt'), Erin, and several owners — one of them after hearing it sound poor on budget amps. The other camp says moderate amps are fine at sane levels: SoundStage's 60 W Hegel H95 drove it to loud levels in a living room, Klaus Eulenbach's Chord Anni had 'absolutely zero issues', one owner uses a Topping PA5 at 0.5 m, and another a 50 W SMSL at 3 m. One owner who gave it 'all the power you could dream of' says more power didn't change its bass.

Well regarded. ASR found it dense and solid with widely spaced binding posts, Stereophile measured the cabinet as effectively inert, and What Hi-Fi gave build five stars. The caveat is the woofer at high volume. A reported failure came from an owner running it full-range from 400 W Hypex monoblocks at around 95 dB, with the subwoofer crossed at 50 Hz, and owners warn that the drivers don't tolerate heavy bass played loud.

“Speaker also feels quite dense and solid which is good.”

amirm, Audio Science Review

“confirmed that the enclosure was effectively inert (fig.3), even more so than the original, which had performed well on this test.”

John Atkinson, Stereophile

“suddenly the left side bass went quiet and I could very visibly see the driver excursion was stuck.”

Esquyvren, r/audiophile (400 W Hypex monoblocks, ~95 dB, full-range)

Mostly seen as a benchmark at its price: What Hi-Fi calls it the class leader, TNW isn't sure anything at $1,500 cleanly beats it, and Stereophile calls its measurements superb even before you consider the price. A vocal minority call it overrated. The practical objection is that a $1,599 pair plus the amplifier and subwoofer it wants is not a budget system, and it is often on sale near $1,000.
