Short answer: the AsciLab C8C. It ranks #1 of 119 powered bookshelf speakers by sound quality (rated 4.9/5); the ADAM Audio T8V ranks #94 (rated 3.9/5).
The AsciLab C8C is the more accurate, 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 measured preference score, a predictor of how neutral it sounds, is 7.70 against 4.65 for the ADAM Audio T8V. Its bass reaches about 30.8Hz before falling 3dB, against 39.6Hz for the ADAM Audio T8V. The tradeoff: The result applies to the revised measured configuration; confirm that the speaker’s tuning matches it.
Why pick the ADAM Audio T8V: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. The tradeoff: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives.

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.
