Short answer: the HEDD Type 20 MK2 on measured sound quality, the ADAM Audio T7V on price. The HEDD Type 20 MK2 ranks #26 of 119 powered bookshelf speakers, rated 4.5/5, at $4,798. The ADAM Audio T7V ranks #95, rated 3.9/5, at $579.98, $4,218.02 cheaper.
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 tradeoff: Correct listening height is important for the two-way crossover.
The HEDD Type 20 MK2 is the better-sounding, deeper-bass choice. The measured ported configuration reaches 35.2Hz at -3dB and scores 7.69 with an ideal subwoofer. Its bass reaches about 32Hz before falling 3dB, against 65Hz for the ADAM Audio T7V. The catch: These results are for ported operation, not every bass or phase setting.

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: The measured ported configuration reaches 35.2Hz at -3dB and scores 7.69 with an ideal subwoofer. A 2.4dB response span from 300Hz to 5kHz supports broadly balanced mids, while ported operation reduces deep-bass strain compared with the sealed setting in the review. Measured bass extension of 32Hz (-3dB).
Cons: These results are for ported operation, not every bass or phase setting. Horizontal asymmetry and vertical crossover behavior make orientation and listening position important. Distortion rises at higher output, and linear-phase processing can add latency for live monitoring.
