A long-time staple in many a contractor’s product line card, ceiling speakers have come a long way from providing bandwidth-limited background music to being full range, high-fidelity audio reproducers. These days they come in a variety of shapes and sizes, including the classic round with a back can, square, or rectangle acoustical tile size, and even pendants that hang down from the rafters. Some manufacturers have also created subwoofer options.
Many manufacturers offer more selections than the model highlighted in this overview. It’s recommended that you visit their websites for more in-depth information.
