A speaker typically contains several key components: a diaphragm, which vibrates to create sound waves; a voice coil, which interacts with a magnetic field to produce movement; a magnet, providing the necessary magnetic field; and a frame or enclosure that holds these parts together. Additionally, some speakers may include a crossover network to manage different frequency ranges, directing them to appropriate drivers like woofers and tweeters. Together, these components work to convert electrical signals into audible sound.

Speaker cable can have an insulator that could be any color. The wire inside is typically silver, copper or gold colored.
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
