The DAP design ceiling speaker series consists of three models of 100V 2-way ceiling speakers with an ultra-slim design. They are available in 4-, 5-, and 6-inch models, all featuring ½ inch tweeters and built-in crossover networks. The sleek grille design with a very thin edge and limited grille depth makes these speakers nearly invisible when mounted. The elegant yet sturdy grille is held in place by strong neodymium magnets. This makes installation and removal very easy, yet reliable enough to keep the grille in place throughout the speaker's lifespan. The speaker is mounted in the ceiling simply using a quick-mount mechanism that can be tightened with four screws behind the front grille.
