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 border and limited grille depth, makes these speakers nearly invisible when installed. The elegant yet sturdy grille is held in place by strong neodymium magnets. This allows for easy yet reliable installation and removal, keeping the grille securely in place throughout the speaker's lifespan. The installation of the speaker in the ceiling is straightforward, using a quick-mount mechanism that can be tightened with four screws behind the front grille.
