Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Goldmund leverages proprietary software, including "Proteus" and "Leonardo," to mathematically model and design speakers, minimizing human intervention and enabling digital room correction without microphones.
