Short answer: the KEF LSX II LT. It ranks #26 of 67 powered bookshelf speakers by sound quality, rated 4.0/5, at $549.99; the Kanto Tuk G2 ranks #32, rated 3.9/5, and costs $899.99, which makes this an easy call rather than a real tradeoff.
Why pick the Kanto Tuk G2: Bass reaches about 52Hz at -3dB and 42Hz at -10dB in Erin’s measurements, legitimate extension from a 5.25-inch woofer. The tradeoff: On-axis response is uneven, with elevated upper bass around 80 to 100Hz, a forward midrange near 800Hz to 1.5kHz and further ripples through the treble.
The case for the KEF LSX II LT: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. The catch: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
Buy the KEF LSX II LT. It is rated higher for sound quality than the Kanto Tuk G2 and costs less, so the other one has nothing left to offer.

Kanto Tuk G2: $899.99 per pair eBay
Pros: Bass reaches about 52Hz at -3dB and 42Hz at -10dB in Erin’s measurements, legitimate extension from a 5.25-inch woofer. The predicted in-room response is fairly even from the upper bass through the treble, which lifts its preference score to about 4.6 on its own and 6.7 with an ideal subwoofer. Connections cover most desk and living room sources: optical, two RCA inputs, USB-C from a computer and Bluetooth 5.4 with aptX Adaptive, plus a subwoofer output with an 80Hz low-pass, a remote and a USB charging port. Measured bass extension of 52Hz (-3dB).
Cons: On-axis response is uneven, with elevated upper bass around 80 to 100Hz, a forward midrange near 800Hz to 1.5kHz and further ripples through the treble. Horizontal dispersion widens abruptly around 2 to 2.5kHz before narrowing again, and the vertical listening window is narrow, so keep the AMT tweeter near ear height. Compression grows at 96dB and becomes severe near 102dB, with distortion rising sharply at high levels, so it sounds best as a nearfield or small room speaker at moderate volume.

KEF LSX II LT: $549.99 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 3.93 standalone and 6.16 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. 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.
