Short answer: the JBL 305P MKII. It ranks #17 of 100 powered bookshelf speakers by sound quality (rated 4.3/5) at $289 and is still sold new; the Kanto YU6 ranks #40 (rated 3.9/5) and is discontinued, so it is only an option used. The Kanto YU6’s replacement, the Kanto YU6 G2, is rated 3.9/5.
The JBL 305P MKII is the more accurate pick. Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.38 against 4.28 for the Kanto YU6. The tradeoff: The 3.3dB midrange span and rising response show it is not perfectly neutral.
Why pick the Kanto YU6: ASR’s measurements give preference scores of 4.28 standalone and 6.89 with an ideal subwoofer, stronger than several smaller lifestyle pairs. The tradeoff: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419.
Buy the JBL 305P MKII. It is rated higher for sound quality, and the Kanto YU6 is discontinued, so it is only available used.

The Two Speakers In Full
JBL 305P MKII: $289.00 per pair Amazon eBay
Older model: the JBL LSR305 (ranked lower, rated 4.2/5).
Same family: the JBL 306P MKII (larger bookshelf, rated 4.1/5) and the JBL 308P MKII (larger bookshelf, rated 4.4/5).
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

Kanto YU6: $380.00 per pair Discontinued Amazon eBay
Newer model: the Kanto YU6 G2, estimated 3.9/5.
Same family: the Kanto YU2 (smaller bookshelf, estimated 3.4/5) and the Kanto YU4 (smaller bookshelf, rated 3.3/5).
Pros: ASR’s measurements give preference scores of 4.28 standalone and 6.89 with an ideal subwoofer, stronger than several smaller lifestyle pairs. Phono input, optical connections and remote control make it useful for a simple multi-source system. The overall response trend is close to level rather than strongly tilted.
Cons: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419. Bass reaches -3dB around 75Hz, so the preference model’s 58Hz LFX value should not be quoted as full-level bass extension. A subwoofer improves bandwidth but does not remove tonal irregularities. Discontinued.
