Short answer: the Totem Kin One, if you are buying new. The KEF Q150 ranks higher than it (#26 vs #54 of 88 bookshelf speakers, 3.7/5 vs 3.0/5) but is discontinued, so only consider it used; the Totem Kin One is still sold new at $600.
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. The tradeoff: 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 case for the Totem Kin One: Compact two-way design with a 1” titanium-infused soft dome tweeter and 4” MHex cone woofer, available in distinctive colorways beyond the usual black/white. The catch: Real-world sensitivity measured significantly below the manufacturer’s spec (about 83.4dB measured versus 89dB claimed).
Buy the Totem Kin One new; the KEF Q150 is no longer sold new, so it only makes sense as a used find.

KEF Q150: $350 per pair Discontinued Amazon eBay
Newer model: the KEF Q1 Meta, ranked lower, rated 3.6/5.
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.

Totem Kin One: $600 per pair Sky by Gramophone eBay
Pros: Compact two-way design with a 1” titanium-infused soft dome tweeter and 4” MHex cone woofer, available in distinctive colorways beyond the usual black/white. Surprisingly spacious, wide sound for its tiny size: horizontal dispersion of about ±75° through the midrange gives real envelopment and soundstage width. Reasonably good overall directivity, meaning it takes well to EQ correction. Pairs well with an EQ-capable streaming amp (the reviewer specifically suggests something like a WiiM Amp), which can smooth out its main tonal issues with just a few bands of correction. Crossing over to a subwoofer around 80Hz measurably reduces midrange distortion and improves resolution. For a 4” woofer, distortion performance up to about 88dB is reasonable and shouldn’t be judged against larger-driver speakers. Measured bass extension of 91Hz (-3dB), with a measured sensitivity of 83.4dB.
Cons: Real-world sensitivity measured significantly below the manufacturer’s spec (about 83.4dB measured versus 89dB claimed). Treble rolls off sharply above about 8kHz, an unusually attenuated top end that the reviewer wasn’t sure was even an intentional design choice. A dip around 600Hz-1kHz paired with a nearby resonance (likely port-related) gives a combination of hollow and forward character depending on the exact frequency. Bass rolls off around 80-90Hz (F3 91Hz, F10 59Hz), typical for a compact 4” woofer, so a subwoofer is essential for any real bass. Vertical placement has a real sweet spot: going too far above or especially below the tweeter axis noticeably changes the tonal balance. Distortion rises substantially at 96dB and the port/woofer begin struggling at extreme low frequencies and volumes. Best aimed directly at the listener given how quickly the treble rolls off; toeing it out requires EQ compensation to avoid sounding dull.
