Watts and volume - how do they relate to one another?

The number of watts that you will need depends onClick to fill in our simple enquiry form a number of factors including your style of music, the size of the venue, the location (indoors or out) and the number of people in the audience (bodies absorb sound!).

Although technically (all things being equal) if you double the number of Watts you double the sound pressure level (SPL), our ears don't necessarily perceive the volume as twice as loud. The reasons for this are quite complicated but as a general rule, doubling the number of Watts increases perceived volume by around 30%.
