Revision as of 09:39, 22 July 2024 by JoernNettingsmeier (talk | contribs) (Created claim: Property:P66: Individual speakers can only solve very simple sound reinforcement problems. Combining speakers in a controlled way allows us control directivity and scale up sound pressure levels to the needs of larger venues.)
Individual speakers can only solve very simple sound reinforcement problems. Combining speakers in a controlled way allows us control directivity and scale up sound pressure levels to the needs of larger venues.
