Short answer: the HEDD Type 20 MK2 for better sound quality, the Yamaha HS8 for the lower price. The HEDD Type 20 MK2 ranks #7 of 66 powered bookshelf speakers at $4800. The Yamaha HS8 ranks #15 at $678.28, $4121.72 cheaper.
What the Yamaha HS8 offers: ASR’s Klippel measurements show a notably neutral predicted in-room response, smooth horizontal directivity, and strong bass extension for a studio monitor: about 44Hz at -3dB and 35Hz at -10dB. Its Spinorama preference score rises from 4.95 full-range to 6.68 with a subwoofer, and the rear room-control switches provide some placement adjustment. Watch for: There is still some midrange unevenness and the vertical listening window is much narrower than the horizontal one, so ear height matters. The rear port and cabinet depth complicate close-wall placement, there is no DSP or automatic room correction, and the price is per speaker rather than per pair.
What the HEDD Type 20 MK2 offers: CEA2034 spinorama shows a nice flat on-axis response with a very smooth directivity index, plus an intentional boost at 40-50Hz for extra bass warmth. Predicted in-room response is nice and smooth. Early reflections integrate very cleanly with the direct sound, rated “very nice” by the reviewer. Distortion at 86dB SPL/1m is very good, staying well below the reviewer’s audibility threshold across the range. Its open-port configuration measures notably lower bass distortion than the same speaker run in closed-port mode. Watch for: Horizontal beamwidth is asymmetric (+60/-80 degrees depending on reference point) and narrows above 10kHz. Vertical directivity means listening position needs to stay at or below the reference axis for accurate tonal balance. At 96dB SPL/1m, distortion rises broadly across the spectrum, exceeding the reviewer’s audibility threshold over a wide frequency range - a notably worse result than at 86dB. Cumulative spectral decay (waterfall) shows resonances lingering in the 500Hz-2kHz region. Switching to closed-port mode increases bass distortion further, so the open-port configuration is preferable.
Buy the Yamaha HS8 if the price matters more than sound quality. Buy the HEDD Type 20 MK2 if sound quality matters more than the price.
