Is 1000 watts loud for speakers?

I'm curious to know if 1000 watts is considered loud for speakers. I understand that wattage measures the power output of an audio system, but does a higher wattage necessarily mean louder sound? Is there a threshold beyond which the increase in wattage doesn't significantly impact the volume or is it more about the efficiency of the speakers themselves? I'm trying to balance my desire for powerful audio without overwhelming my space or causing potential damage to my hearing. Can you provide some insights into how wattage relates to speaker loudness and what factors I should consider when selecting speakers for my needs?
