For each speaker, you'll get a high-frequency compression driver, a horn flare, a 15" low frequency cone, a crossover network, a Zobel network for the woofer, a compensaion network for the compression, input terminal cup, and a tube for the port(s).What you'll need to complete the kit will be materials and supplies for the cabinet, damping material, bolts and screws to build cabinet and install drivers, and tools. Some caulking would be a good idea too to seal all the internal seams.
