Short answer: the Kii THREE if sound quality matters most, the Kali Audio IN-8 V2 if price matters most. The Kii THREE ranks #3 of 79 powered bookshelf speakers, rated 4.9/5, at $16,970. The Kali Audio IN-8 V2 ranks #30, rated 4.4/5, at $998, $15,972 cheaper.
The Kii THREE is the more accurate, deeper-bass pick. Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.70 standalone and 8.35 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 7.70 against 5.36 for the Kali Audio IN-8 V2. Its bass reaches about 28Hz before falling 3dB, against 44Hz for the Kali Audio IN-8 V2. Watch for: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress.
What the Kali Audio IN-8 V2 does well: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. The tradeoff: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward.
Buy the Kii THREE if sound quality matters more than the price. Buy the Kali Audio IN-8 V2 if the price matters more than sound quality.

The Two Speakers In Full
Kii THREE: $16,970 per pair Vintage King eBay
Pros: Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.70 standalone and 8.35 with an ideal subwoofer. Cardioid control reduces rearward low-midrange energy, while measured -3dB extension of 29.3Hz provides convincing full-range bass in a compact system. Measured bass extension of 28Hz (-3dB).
Cons: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress. The reviewer preferred a small treble reduction, so the high score is not a promise of ideal tonal balance for every listener. Linear-phase operation adds latency, and the system is expensive.

Kali Audio IN-8 V2: $998 per pair Amazon eBay
Smaller model: the Kali Audio IN-5 (rated 4.2/5).
Pros: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Measured -3dB extension of 45.4Hz provides useful bass; boundary settings assist placement. The front port allows placement near a wall without port noise problems. Measured bass extension of 44Hz (-3dB), with a measured sensitivity of 89dB.
Cons: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward. Bass and limiter behavior constrain high-level playback. These measurements apply to the V2, not the first-generation IN-8. On-axis, the 4 to 5kHz range sounds forward; Kali recommends about 10° of toe-out, and some EQ helps.
