Short answer: the Ascend Sierra 1 v2. It ranks #3 of 88 bookshelf speakers by sound quality, rated 4.7/5, at $1,000; the Tekton Troubadour ranks #24, rated 3.8/5, at $1,000. With prices this close, go by the sound-quality ranking rather than the cost.
What the Ascend Sierra 1 v2 does well: Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer, mated by a 4th-order acoustic crossover rather than a stock textbook design. The catch: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material.
What the Tekton Troubadour does well: 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. The tradeoff: 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.
One note: the Tekton Troubadour is discontinued, but it still ranks #24 of 88 bookshelf speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Ascend Sierra 1 v2. It is rated higher for sound quality than the Tekton Troubadour at the same price, which makes it the one to get unless you need something the other one does better.

Pros: Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer, mated by a 4th-order acoustic crossover rather than a stock textbook design. In-room response is extremely linear (the reviewer called it “textbook”) a clear step up from the earlier V1, which had boxiness around 700Hz-1kHz and sibilance around 4-6kHz. Preference score of 8.4 with a subwoofer (6.8 without), which the reviewer calls topnotch. Wide, even horizontal radiation of about ±70° up to 6kHz. Better vertical directivity than its tweeter-to-woofer spacing would suggest, thanks to the steep 4th-order crossover slopes. No mechanical noise, port chuffing, or woofer bottoming even driven to 96dB/1m. In a three-way comparison against the Dynaudio Emit 20 and a Revel bookshelf model (all around $1,000/pair), measured as the most linear of the three and was the reviewer’s personal pick over both, despite the Dynaudio’s deeper bass and higher output capability. Independent ASR Klippel measurements corroborate Erin’s findings: superb off-axis response with only slight on-axis variations, and an in-room response the reviewer called “incredibly smooth and accurate. Amazing for a non-DSP speaker.” Distortion above 200Hz at 86dB/1m is very low for the class. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 81.5dB.
Cons: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material. Diffraction dips appear around 3kHz and 5-6kHz, and the 1” dome tweeter starts beaming above roughly 6.7kHz, narrowing the soundstage radiation in the top octave: a straightforward consequence of dome size rather than a design flaw. At 96dB/1m the 5.25” midwoofer shows increased distortion in the midrange, likely tied to motor topology; high-passing to a subwoofer around 80Hz largely clears it up. Moderate sensitivity (~81-82dB average) with a 7-ohm minimum impedance. ASR’s power-sweep testing found response holds steady up to 96dB SPL/1m, but pushing to 102dB causes midbass below 400Hz to sag with distortion “through the roof”: a harder output ceiling than the 96dB tests alone suggest. Vertical directivity also narrows above about 1kHz, so the reviewer recommends staying at tweeter-axis height for best results.

Tekton Troubadour: $1,000 per pair Discontinued eBay
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. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.
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. Discontinued.
