Speaker products are audio frequency electromagnetic transducers used primarily to turn energy in the format of an electrical signal into mechanical compression waves travelling through an atmospheric air environment for reproduction of speech, music, or similar material. Products designed for general purpose reproduction of partial regions of the human audible frequency range (subwoofers, woofers, tweeters, etc.) are included, as well as full range products and special purpose transducers tailored for headset or in-ear applications.

Every audio power amplifier design starts with the same fundamental challenge: converting a low-voltage line-level signal into the high-current drive required by a reactive…
