Short answer: the Neumann KH 150. It ranks #8 of 119 powered bookshelf speakers by sound quality, rated 4.8/5, at $3,398; the HEDD Type 20 MK2 ranks #26, rated 4.5/5, and costs $4,798, which makes this an easy call rather than a real tradeoff.
The Neumann KH 150 is the more accurate option. Studio monitors with exceptionally accurate sound and solid bass, plus room tuning for critical listening. Its measured preference score, a predictor of how neutral it sounds, is 6.65 against 6.11 for the HEDD Type 20 MK2. Watch for: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance.
The HEDD Type 20 MK2 is the deeper-bass option. Three-way studio monitors with balanced mids, useful deep bass, and switchable ported or sealed bass for different needs. Its bass reaches about 32Hz before falling 3dB, against 39.6Hz for the Neumann KH 150. Watch for: These results are for ported operation, not every bass or phase setting.
Buy the Neumann KH 150. It is rated higher for sound quality than the HEDD Type 20 MK2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
