Short answer: the Airpulse A100. It ranks #25 of 67 powered bookshelf speakers by sound quality, rated 4.0/5, at $999.99. The Kanto Tuk G2 ranks #32, rated 3.9/5, at $899.99, $100 cheaper, which does not close the gap in sound quality.
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. Watch for: 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.
What the Airpulse A100 does well: ASR’s Klippel data gives a 2.9dB midrange span and scores of 4.56 standalone and 7.08 with an ideal subwoofer. The catch: Bass reaches -3dB around 63Hz, so lower notes need a subwoofer for full weight.
Buy the Airpulse A100. It is rated higher for sound quality, and the $100 saving on the Kanto Tuk G2 is not enough to make up the difference.

The Two Speakers In Full
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.

Airpulse A100: $999.99 per pair Amazon B&H Photo Video eBay
Pros: ASR’s Klippel data gives a 2.9dB midrange span and scores of 4.56 standalone and 7.08 with an ideal subwoofer. The ribbon tweeter and five-inch woofer provide a distinctive compact powered system, with remote control and a subwoofer output simplifying everyday use. Measured bass extension of 63.0Hz (-3dB).
Cons: Bass reaches -3dB around 63Hz, so lower notes need a subwoofer for full weight. Listening-window narrow-band deviation of 0.419 shows more local tonal variation than the leading monitors. Rear tone controls are less flexible than parametric EQ or room correction. Neither the ribbon tweeter nor a directivity-index summary establishes uniquely wide or perfectly controlled dispersion.
