Term: Active System

Definition: An active system is a term not really used as far as i know... because "Active" means "it has an amp built in", so to have active speakers it means each speaker has an amplifier built into it, which either means they run on batteries, or plug into a power socket. This is an advantage for small systems because you don't require a high-powered amplifier connected.

To have an "active system" however, must mean that the speaker components of a larger system are active, because the only other part to contain an amp should be the amplifier itself!
