At Podspeakers we would like to help you getting the right speaker set up. Part of getting there is choosing the right speakers. To choose the right speakers we need to decide whether you need an amplifier or not.
The wireless loudspeakers use Bluetooth to connect to your phone, tablet, or computer. They are "active" speakers have a built in power amplifier and just need a power source or battery to operate. An active speaker is essentially an all-in-one system that powers your speakers. The amplifier is built in to the speaker cabinet.
