Short answer: the KEF LSX II LT. It ranks #36 of 108 powered bookshelf speakers by sound quality, rated 4.0/5, at $749.99; the Kanto Tuk G2 ranks #44, 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: A desk or living room pair with solid bass for its size, optical, USB-C, aptX Adaptive Bluetooth and a subwoofer output. 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: Compact wireless speakers with HDMI and optical inputs, made for a TV or desk, with sound that stays even across a sofa. 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, which makes it the one to get unless you need something the other one does better.
