Short answer: the Kii THREE if sound quality matters most, the ADAM Audio T7V if price matters most. The Kii THREE ranks #3 of 118 powered bookshelf speakers, rated 4.9/5, at $16,970. The ADAM Audio T7V ranks #95, rated 3.9/5, at $579.98, $16,390.02 cheaper.
The Kii THREE is the better-sounding, 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 bass reaches about 28Hz before falling 3dB, against 65Hz for the ADAM Audio T7V. The catch: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress.
What the ADAM Audio T7V does well: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. The catch: Correct listening height is important for the two-way crossover.
Buy the Kii THREE when sound quality outweighs the price for you, and the ADAM Audio T7V when the price outweighs sound quality instead.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

The Two Speakers In Full
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.

ADAM Audio T7V: $579.98 per pair Amazon eBay
Same family: the ADAM Audio T5V (smaller bookshelf, rated 4/5) and the ADAM Audio T8V (larger bookshelf, ranked higher, rated 3.9/5).
Pros: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. Basic tonal controls and analog connections suit a straightforward nearfield system. Measured bass extension of 65Hz (-3dB).
Cons: Correct listening height is important for the two-way crossover. Basic shelf controls offer less adjustment flexibility than parametric room correction.
