#7 HEDD Type 20 MK2: $4800 Bhphotovideo eBay

Pros: 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.

Cons: 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.

How it compares: Just above it: Genelec 8351B - $4350 more, 350W less output power. Just below it: Genelec 8050B - $1000 cheaper, 630W less output power.
