(Reading time: 1 - 2 minutes)

Welcome back to The Blackboard Sessions! This week we take a look at selecting the right sized amp for our loudspeaker systems. Rather than having a discussion between Class A/B/D amps and finding the benefits of each, this is a more general discussion on how to measure and calculate your power requirements. Doing this will ensure that you are not:

 A. Underpowering your system, and thus not getting the desired results (clipping).

 B. Overpowering your system where it isn’t necessary.
