Short answer: the Kanto Tuk G2. It ranks #32 of 67 powered bookshelf speakers by sound quality, rated 3.9/5, at $899.99. The Adam Audio A4V ranks #43, rated 3.6/5, at $599.99, $300 cheaper, which does not close the gap in sound quality.
Why pick the Adam Audio A4V: Compact monitor with onboard DSP, placement controls and room-correction integration. Watch for: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547.
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 catch: 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.
Buy the Kanto Tuk G2. It is rated higher for sound quality, and the $300 saving on the Adam Audio A4V is not enough to make up the difference.

Adam Audio A4V: $1,199.98 per pair B&H Photo Video eBay
Pros: Compact monitor with onboard DSP, placement controls and room-correction integration. ASR’s Klippel data gives a -3dB point around 59Hz and preference scores of 3.92 standalone and 6.33 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed.
Cons: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547. The native response should therefore not be called smoothly neutral. Correction potential is not the same as stock performance, and analog audio inputs mean a separate interface is needed for USB sources.

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.
