Short answer: the KEF LS50 Meta for better sound quality, the Tekton Troubadour for the lower price. The KEF LS50 Meta ranks #4 of 34 bookshelf speakers at $1599. The Tekton Troubadour ranks #13 at $1000, $599 cheaper.
What the KEF LS50 Meta offers: Uni-Q concentric driver mounts a 1” vented aluminum dome tweeter at the center of a 5.25” aluminum cone woofer, rated 79Hz-20kHz+. Watch for: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
What the Tekton Troubadour offers: Offset in-phase array of 2x 5.25” mid-woofers and 3x 1” dome tweeters gives good on-axis linearity (within about ±2.5 dB) and a wide vertical listening window (about ±20°), so seating height isn’t fussy. Watch for: Forward, elevated upper-midrange presentation from increased off-axis energy in the 2-8 kHz range, centered around 4 kHz, that can read as hot or aggressive depending on the room and listener; a couple bands of EQ can tame it.
Buy the KEF LS50 Meta if sound quality matters more than the price. Buy the Tekton Troubadour if the price matters more than sound quality.

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 $1,000 (a frequent sale price versus $1,600 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.”
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.

Tekton Troubadour: $1,000
Pros: Offset in-phase array of 2x 5.25” mid-woofers and 3x 1” dome tweeters gives good on-axis linearity (within about ±2.5 dB) and a wide vertical listening window (about ±20°), so seating height isn’t fussy. Bass extension is solid for a stand-mount this size: F3 around 51 Hz, F10 around 39 Hz, with distortion staying below 3% THD down to about 40 Hz at 96 dB. Made in the USA. Asymmetrical tweeter/mid-woofer placement broadens horizontal dispersion versus a conventional symmetric layout.
Cons: Forward, elevated upper-midrange presentation from increased off-axis energy in the 2-8 kHz range, centered around 4 kHz, that can read as hot or aggressive depending on the room and listener; a couple bands of EQ can tame it. Multitone distortion climbs to about 10% around 1 kHz at higher output, attributed to the 4-inch mid-range drivers. Because the driver layout is offset rather than mirror-imaged, left/right placement and toe-in matter more than with a standard symmetric bookshelf design.
