The term Surface Speakers refers to more traditional designs that are not recessed into walls or ceilings but instead fixed in a form of wood or metal cabinets. Bookshelf mounted, large floor standing speakers and subwoofer and satellite systems have certain acoustic advantages over hidden speakers and by their nature are easier to install. Because the speaker components are mounted in an optimal size enclosure the immediate improvement is in a lower more controlled bass response.
The larger size of cabinet has a direct result on the bass response so smaller designs require a dedicated subwoofer that can be hidden away out of site to produce the lower bass. Active SUB SAT designs like the Acoustic Energy AEGO range offer a complete all in one solution, allowing the system to connected directly to a TV or music player with no amplifier required.
