Short answer: the Neumann KH 310 A. It ranks #20 of 119 powered bookshelf speakers by sound quality, rated 4.6/5, at $4,998. The HEDD Type 20 MK2 ranks #26, rated 4.5/5, at $4,798, $200 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Neumann KH 310 A: Sealed three-way studio monitors with balanced sound, useful deep bass, and low distortion even when played hard. The tradeoff: Its measured tonal balance is not as even as the Neumann KH 150 or the best coaxial alternatives.
Why pick the HEDD Type 20 MK2: Three-way studio monitors with balanced mids, useful deep bass, and switchable ported or sealed bass for different needs. It has an adjustable EQ, which the Neumann KH 310 A lacks. Watch for: These results are for ported operation, not every bass or phase setting.
Buy the Neumann KH 310 A. It is rated higher for sound quality, and the $200 you would save on the HEDD Type 20 MK2 does not close the gap.
