This Fix-It Guide on speaker repair tells how a speaker works, what often goes wrong, how to identify a speaker problem, and what parts and tools you will need to fix it. It then gives simple step-by-step instructions for a way to disassemble a speaker, the way to repair a damaged speaker cone, and the way to get correct speaker polarity (phasing). Fortunately, speakers are relatively simple in design and can be fixed easily. This guide also refers to other Fix-It Guides for specific repairs.

Audio speakers for a home stereo or entire home entertainment system amplify the sound generated from another component of the system. the standard speaker may be a collection of complementary parts. the standard enclosure (speaker case) features a 6- to 15-inch-diameter cone woofer for low frequencies, a 3- to 6-inch-diameter dome or cone mid-range driver (commonly called a speaker), and alittle tweeter for top frequencies. Audio signals move along speaker cables to a terminal block at the rear of the enclosure. Once inside, a crossover network divides incoming frequencies into the acceptable ranges, sending each to the right driver. Drivers then convert this input into mechanical movement of the cone which, in turn, moves the air during a way that’s detected by your ears as sound.
