DIY speaker kits typically include the following components:

* Cabinet: The enclosure that holds the driver(s) and crossover.
* Driver(s): The speaker(s) that produce the sound waves. Kits may include woofers, tweeters, and/or midrange drivers, depending on the type of speaker being built.
* Crossover: A network of components that divides the audio signal into separate frequency bands and directs each band to the appropriate driver.
* Terminal cup: A mount for attaching the speaker wire to the speaker.
* Grills: A removable cover for the front of the speaker that protects the driver(s) from damage.
* Hardware: Screws, nails, glue, and any other miscellaneous hardware needed to assemble the speaker.
* Instructions: A detailed set of step-by-step instructions for assembling the speaker.

Some kits may also include additional components such as foam gaskets, port tubes, and/or damping material.
