Short answer: pick the KEF LSX II LT if you want sound quality that has been measured and ranked; the Kanto YU6 G2 is unmeasured so far, so its case rests on features and price.
What the Kanto YU6 G2 offers: The second generation YU6 swaps the Kevlar woofers for 5.25” abaca paper cone woofers alongside 1” silk dome tweeters, and raises amplifier power to 130W RMS (200W peak) from the original’s 100W RMS.
What the KEF LSX II LT brings: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments.
On paper: The KEF LSX II LT is rated down to 54Hz against 55Hz, though makers quote these at different tolerances.
Price: the Kanto YU6 G2 lists at $549.99 and the KEF LSX II LT at $479.99.
Buy the KEF LSX II LT if you want a speaker whose sound quality has been measured and ranked. It also has deeper rated bass and HDMI ARC.
Buy the Kanto YU6 G2 if you want RCA inputs and an aux input, and you can wait for measurements to confirm how it sounds.

The Two Speakers In Full
Kanto YU6 G2: $549.99 per pair Kanto eBay
Older model: the Kanto YU6 (rated 3.9/5).
Pros: The second generation YU6 swaps the Kevlar woofers for 5.25” abaca paper cone woofers alongside 1” silk dome tweeters, and raises amplifier power to 130W RMS (200W peak) from the original’s 100W RMS. Inputs cover RCA with a switchable phono preamp, optical and USB-C audio at 24 bit/96kHz, 3.5mm aux and Bluetooth 5.3 with AAC. A subwoofer output engages an automatic 80Hz crossover, and a USB-C port charges a phone. Includes a remote, speaker wire and swappable left and right channels.
Cons: Not on sale yet: Kanto lists it as coming soon. No independent measurements have been published, so it can’t be compared with the original YU6, which ASR measured. Its rated response starts at 55Hz, against 50Hz for the original YU6, so a subwoofer still helps for deep bass. Kanto doesn’t publish sensitivity or maximum output.

KEF LSX II LT: $479.99 per pair Amazon eBay
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 4.81 standalone and 7.03 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Horizontal and vertical dispersion both reach about ±60°, giving a broad sweet spot for more than one seat. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.
