Short answer: the Mesanovic CDM65 on measured sound quality, the HEDD Type 20 MK2 on price. The Mesanovic CDM65 ranks #2 of 67 powered bookshelf speakers at $5998. The HEDD Type 20 MK2 ranks #18 at $4800, $1198 cheaper.
What the Mesanovic CDM65 offers: Erin’s measurements show a very even 1.1dB span from 300Hz to 5kHz and an 8.08 ideal-subwoofer preference score, strong evidence for natural tonal balance. Measured -3dB bass extension is 36.6Hz. Switchable cardioid operation offers useful control of rearward radiation; an optional WiSA hub adds wireless system integration. Watch for: Cardioid operation and bass tuning affect placement and output, so use the appropriate mode for the room. A subwoofer is still useful for deep bass at high levels. These are substantial, roughly 14.5kg cabinets, and the optional hub adds cost rather than being necessary for wired playback.
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.
