A sound system with a power rating of 500 watts RMS (root mean square) is considered moderately loud, providing a clear and warm sound that can fill a medium to large room. However, the perceived loudness would also depend on factors like the room’s acoustics and the listener’s distance from the speakers. To achieve a high SPL (sound pressure level) and a loud sound, a more powerful system, in the kilowatt range, would be required.
