My lasted project had a customer contact me about his home renovation and wanting to setup up his home entertainment system. He like many others wanted a simple hidden yet effective instillation without sacrificing incredible sound. We went through and installed all custom hand made front and center speakers while utilizing Dayton audio rear in wall speakers. We also wanted to hide the sub woofer/enclosure as best we could and we wanted to keep it from being obtrusive and ruin the flow of the room. I finallized a design in which we would mount a 15" dayton subwoofer in a sealed enclosure mounted in the ceileing. Hiding the woofer in the ceiling allowed us to hide the sub and enclosure and minimize the intrusive feel of a large stand alone enclosure.
