Power Background
The basis for the entire electric guitar revolution has been the use of electricity to provide the necessary energy to create, modify, and produce the sounds made by the player. Electricity is introduced to the amplifier and a small current is sent to the electric guitar to feed power to the pickups (passive). The pickups generate a magnetic field which is influenced by the vibration of the strings. The fluctuations in the field provide electrical current feedback which is then sent back to the amplifier for processing.
This signal is then modified and adjusted by the amplifier via a preamp phase and any number of post processes before being sent to the power amplifier (tube or solid state) of the amp. From here the final signal is sent as an electrical current to the speaker(s). The speakers are equipped with a magnet which reacts to the electrical current and cause the speaker cone to flex and move which creates vibrations in the air that are heard by the ear.
The electrical signal sent from the amplifier to the speaker(s) varies in power, current, and resistance. A working knowledge of these attributes are needed in order to properly pair speakers with amplifiers and to obtain a desired volume or effect.
