Short answer: the KEF Q11 Meta. It ranks #103 of 188 floorstanding speakers by sound quality, rated 4.0/5, at $2,499.98. The Magnepan LRS+ ranks #149, rated 3.5/5, at $1,300, $1,199.98 cheaper, which does not close the gap in sound quality.
The KEF Q11 Meta is the more accurate, deeper-bass option. 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 measured preference score, a predictor of how neutral it sounds, is 6.72 against 1.27 for the Magnepan LRS+. Its bass reaches about 60Hz before falling 3dB, against 74Hz for the Magnepan LRS+. The catch: 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.
What the Magnepan LRS+ does well: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). The catch: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output.
Buy the KEF Q11 Meta. It is rated higher for sound quality, and the $1,199.98 you would save on the Magnepan LRS+ does not close the gap.

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 KEF R3 Meta and a few dB less than the KEF 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.

Magnepan LRS+: $1300 per pair Magnepan eBay
Pros: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). Delivers a uniquely dramatic and enveloping soundstage with genuinely three-dimensional depth effects that work across all music genres, not just classical or orchestral material as commonly assumed. Extremely tight, locked-in center-phantom imaging when set up correctly. Open-baffle design avoids the “boxy” enclosure coloration of conventional cabinet speakers. Multitone distortion is remarkably consistent from low to high frequency, a characteristic the reviewer hasn’t observed in conventional cone-and-dome speakers. Compression at high output stays modest (about 0.5-1dB) through the midrange and treble, giving roughly 20-26dB of usable dynamic range in that region. At its price, a strong contender for a dedicated secondary listening room, even if not a main-system replacement. Measured bass extension of 74Hz (-3dB), with a measured sensitivity of 85.1dB.
Cons: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output. A robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it. Bass rolls off very quickly (F3 74Hz, F10 67Hz, described as falling off “like a rock”), making a subwoofer an absolute requirement for any low-end content. A roughly 3dB dip in the mid-bass (100-300Hz) region thins out vocal body and fullness compared to a conventional bookshelf speaker. A resonance/bump around 400Hz adds a mild boxy quality, though it responds well to about 2dB of EQ correction. Extraordinarily fussy about exact positioning: both seating height (must align with the acoustic reference point between the panel’s lower tie-down points) and horizontal aiming are unusually critical; moving just a couple of inches can cause treble content above roughly 500-600Hz to nearly vanish. Distinct off-axis cancellation zones exist directly to the sides of the panel, where very little sound is audible at all. Fails badly under extreme dynamic-transient testing in the bass, and the reviewer blew fuses pushing the speaker during testing: not built for high-volume or highly dynamic playback. A genuinely different category from conventional hi-fi speakers, requiring more setup patience and experimentation than a typical monopole design.
