Short answer: the AsciLab C8C. It ranks #1 of 119 powered bookshelf speakers by sound quality (rated 4.9/5); the ADAM Audio T7V ranks #95 (rated 3.9/5).
The case for the ADAM Audio T7V: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. Watch for: Correct listening height is important for the two-way crossover.
The AsciLab C8C is the better-sounding, deeper-bass option. ASR’s revised measurement combines an 8.48 ideal-subwoofer preference score with a 1.7dB response span from 300Hz to 5kHz, supporting highly even vocal and instrumental balance. Its bass reaches about 30.8Hz before falling 3dB, against 65Hz for the ADAM Audio T7V. The catch: The result applies to the revised measured configuration; confirm that the speaker’s tuning matches it.

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.

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.

Pros: ASR’s revised measurement combines an 8.48 ideal-subwoofer preference score with a 1.7dB response span from 300Hz to 5kHz, supporting highly even vocal and instrumental balance. Bass reaches 30.8Hz at -3dB and 23.4Hz at -6dB, giving substantial low-end reach without an added subwoofer. Measured bass extension of 30.8Hz (-3dB).
Cons: The result applies to the revised measured configuration; confirm that the speaker’s tuning matches it. Each cabinet weighs about 27.5kg and needs a substantial stand. Deep extension and excellent tonality do not guarantee unlimited bass output or eliminate the need to adjust placement. The fitted bass-alignment Q of 2.13 is on the peaky side, so bass may sound boomy near the tuning frequency without EQ.
