Short answer: both are discontinued, so this only matters if you are buying used. Used, the Tekton Troubadour is the better pick: it ranks #41 of 160 bookshelf speakers by sound quality (rated 3.8/5), against #49 (rated 3.7/5) for the KEF Q150. If you want one new, the KEF Q1 Meta replaces the KEF Q150 and is rated 3.6/5 at $399.99.
The case for the KEF Q150: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. Watch for: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one: a real preference factor depending on your room’s furnishings.
The Tekton Troubadour is the more accurate choice. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.50 against 4.86 for the KEF Q150. 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 Tekton Troubadour only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the KEF Q1 Meta, which replaces the KEF Q150.

The Two Speakers In Full
KEF Q150: $350 per pair Discontinued Amazon eBay
Newer model: the KEF Q1 Meta, ranked lower, rated 3.6/5.
Older model: the KEF Q100 (ranked lower, rated 2.4/5).
Same family: the KEF Q350 (larger bookshelf, rated 3/5), the KEF Q250c (smaller center, rated 3.9/5) and the KEF Q650c (larger center, rated 3.7/5).
Pros: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. Exceptional soundstage depth, a hallmark of KEF’s coaxial designs that the reviewer says few other speakers match. Bass extension reaches into kick-drum territory, respectable for a compact bookshelf speaker. Resonances present in measurements are consistent across on- and off-axis readings, meaning they can be effectively corrected with EQ. Distortion profile is essentially the same whether run sealed or ported, since a subwoofer crossover point sits above where the differences would matter anyway. At its sale price (around $300, sometimes seen at $400), the reviewer considers it a clear step up from his previous budget favorite in this range, the Emotiva B1+, mainly due to the superior soundstage depth. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 85dB.
Cons: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one: a real preference factor depending on your room’s furnishings. A mild dip in the 1-2kHz region reduces vocal fullness somewhat. Unexplained resonances appear in measurements and persist in both sealed and ported configurations, pointing to enclosure or panel vibration rather than the port. Horizontal radiation is narrower than the reviewer generally prefers from KEF’s lineup, with directivity that widens somewhat around 1.2kHz (near a resonance) and again above about 5kHz. Compression testing at high output (102dB) shows significant nonlinearity, especially at lower frequencies: noticeably worse than a comparable Arendal bookshelf speaker costing over twice as much, which held up better until 80Hz. Not intended for loud listening without a subwoofer: the woofer will over-exert itself without a high-pass filter, and the reviewer recommends crossing over at 80-120Hz. At full retail price (around $600/pair), the value proposition is far less certain than at sale pricing. Discontinued.

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.
