The class D audio amplifier market is expected to grow from US$ 2,437.96 million in 2021 to US$ 4,515.74 million by 2028; it is estimated to grow at a CAGR of 9.2% from 2021 to 2028.

Continuous technological innovations in home audio systems and increasing demand for high-performance home theaters are propelling the adoption of class D amplifiers in these systems. The development of gallium nitride (GaN) power transistors has enabled manufacturers to offer high-performance home theater systems, with less cost of production. The GaN transistors exhibit a high conversion rate of energy use along with very effective at high temperatures and they are smaller than silicon MOSFETs, which saves board space cost by eliminating the output LC (inductors & capacitors) filter section. Moreover, developments in the Wi-Fi and Bluetooth speakers, and dedicated speaker dock stations would encourage consumer spending on audio equipment for enhanced audio quality. Bluetooth facilitates wireless connection between stereo systems or soundbars and smartphones, as well as other streaming devices. The rising application of wireless or Bluetooth speakers and home audio systems, coupled with their advanced connectivity features such as online connectivity for music and video content, is bolstering the demand for Wi-Fi and Bluetooth speakers, which is fueling the class D audio amplifier market. Further, growing demand for smart speakers is another factor propelling the class D audio amplifier sales. Smart speakers allow users to stream audio from a variety of sources with an audio request. With the increasing popularity of these speakers, manufacturers are adding audio and voice functionalities such as wireless access points, soundbars, smart thermostats, and smart home hubs to their products. The aforementioned technological developments in audio systems are propelling the demand for audio amplifiers.
