Abstract: A speaker assembly comprising a speaker housing, a speaker mounted in the housing, and at least two threaded studs connected to the housing and speaker and extending away from the external surface of the housing. The studs have an unthreaded, pointed end that is particularly suitable for piercing a ceiling tile with little effort or mess. There are at least two nuts for threading over the studs to secure the studs to a ceiling tile after the studs pierce the tile to attach the housing to the tile, and at least two wire nuts to connect amplifier wires to the tip of the studs. The speaker is mounted to a ceiling tile by piercing the tile with the studs and securing the studs to the other side of the tile with the nuts. The amplifier wires are then connected to the tips of the studs via the wire nuts.
