Acoustic Research is taking the idea of a "bookshelf" speaker to a new extreme with this model from the Home Decor Series. The SAT510, a quite substantial traditional bookshelf speaker, hides inside a fake-but-convincing shell designed to look like four well-read, weathered books. The front of the books have tiny perforations that let the sound through. Other various disguises - like table clocks, lamps, and planters - are also available.
