Short answer: the HEDD Type 20 MK2 on measured sound quality, the Adam Audio T7V on price. The HEDD Type 20 MK2 ranks #18 of 67 powered bookshelf speakers at $4800. The Adam Audio T7V ranks #54 at $289.99, $4510.01 cheaper.
What the Adam Audio T7V offers: 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. Watch for: Correct listening height is important for the two-way crossover. Basic shelf controls offer less adjustment flexibility than parametric room correction.
What the HEDD Type 20 MK2 offers: The measured ported configuration reaches 35.2Hz at -3dB and scores 6.92 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. Watch for: 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.
Buy the Adam Audio T7V if the price matters more than sound quality. Buy the HEDD Type 20 MK2 if sound quality matters more than the price.
If sound quality matters at all to you, skip the Adam Audio T7V. It ranks near the bottom of the 67 powered bookshelf speakers, so look higher up the list instead.
