ABSTRACT:
This speaker enclosure is ideal for public address systems. Primarily, it consists of a ceiling mounted panel, with a conical baffle secured to it, which is used to delay sound off of the back of the speaker, so as not to interfere with the sound from the front of the speaker. It further includes a wire screen, which is used to cut down microphone feedback.
