Large Size Powered Bookshelf Speakers
Ranked #3 of 113 in Large Size Powered Bookshelf Speakers - Kii THREE: $16,970 per pair Vintage King eBay
Same family: the Kii Seven (smaller bookshelf, ranked lower, estimated 4.6/5).
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.

Ranked #23 of 113 in Large Size Powered Bookshelf Speakers - Kii Seven: $7,790 per pair Estimated Vintage King eBay
Same family: the Kii THREE (larger bookshelf, ranked higher, rated 4.9/5).
Pros: A smaller sibling of the Kii Three that uses the same active wave focusing idea: side and rear woofers are driven by DSP to cancel sound going backward, giving a cardioid pattern so nearby walls color the bass far less than with a conventional box. Two 6.5” woofers, a 5” midrange and a waveguided 1” tweeter get 600W of amplification per speaker, and Kii specifies ±0.5dB from 100Hz to 10kHz with bass to 40Hz (-3dB). It accepts analog XLR, TRS and AES digital, and adds Wi-Fi streaming, Bluetooth and Dante, so it works as a studio monitor or a complete wireless hi-fi system.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Kii Three, which shares its cardioid design. Bass extension stops around 40Hz, short of the larger Kii Three, and the optional Kii Control remote costs extra.
