What Is D’Appolito Speaker Design

June 14, 2024

The D’Appolito speaker design is a loudspeaker configuration named after its inventor, Joseph D’Appolito. It involves placing two identical mid-range drivers or woofers on the top and bottom of the tweeter. This configuration is also known as an “MTM” (mid-tweeter-mid) or “D’Appolito array.”

The D’Appolito design aims to improve the directivity and dispersion of sound waves from the speaker, resulting in a more accurate and detailed soundstage. A big advantage is, that the configuration reduces reflections from the floor and ceiling, giving you a more focused and directional sound with fewer room interactions. By using two mid-range drivers or woofers, the speaker is able to produce a more even and extended frequency response, with reduced distortion and improved power handling. 

The D’Appolito configuration is commonly used in high-end home theater and stereo systems, as well as in professional audio applications such as recording studios and sound reinforcement systems.

All our Monitor, Tower, and Center speakers in the 1723 and 1961 lines use this arrangement.
