Danish manufacturers Bang & Olufsen have created their latest speaker system, called the Beolab 15/16. These innovative speakers are designed to be built directly into the wall, thus seamlessly becoming part of the room and creating a surround-sound effect. This sound system features two-way active speakers and an active subwoofer with four-inch speaker units. The Acoustic Balance Principle prevents unwanted vibrations, creating a smoother sound, and the main amplifier features a digital sound engine with six separate amplifiers.
