DIY speaker kits can range in price from around $100 to over $1000, depending on the type and quality of the components included in the kit. Kits that include more high-end components, such as premium drivers and crossover components, will generally be more expensive than those that include more basic components. Additionally, the size and complexity of the speakers can also affect the price of the kit. Kits for smaller, simpler speakers will generally be less expensive than those for larger, more complex speakers.
