Abstract
The present example provides a typically ceiling mounted architectural three way speaker with a typically minimal appearance that includes an integral woofer, a ribbon speaker and a ported enclosure. The three way speaker is constructed so that sound from the woofer and tweeter is created in the enclosure and directed through an aperture shared with a midrange speaker.
