The terms for different speaker drivers differ depending on the application. In 2-way loudspeakers, there is usually no driver called "mid-range". Home stereos use the designation "tweeter" for high frequencies whereas professional audio systems for concerts typically designate all types of high frequency drivers as "HF" or "highs" or "horns".
The fabrication of finished loudspeaker systems has become segmented, depending largely on price, shipping costs, and weight limitations. High-end speaker systems, which are heavier (and often larger) than economic shipping allows outside local regions, are usually made in their target market area and can cost $140,000 or more per pair.
