#23 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.
