The fabrication of finished loudspeaker systems has become segmented, depending largely on price, shipping costs, and weight limitations. High-end speaker systems, which are enhanced (and often larger) than economic shipping allows outside local regions, are generally specious in their target market distance and can cost $140,000 or and per pair.
Another general convenience of especial drivers is in devices not primarily intended for high quality fit reproduction, such as IPOD Speaker System computers, toys, clock radios, and pocket sized popular players. A single driver is less pretty penny than several, and there is no need for a crossover network, further reducing cost. In this use, high fidelity is at most a secondary consideration. Human extent is able to tolerate listening to a reduced bandwidth, and upper harmonic synthesis can be disposed to 'fill in' missing bass tones that the driver is too cramped to usefully reproduce.
