We love the sound of a pair of traditional bookshelf speakers - rich bass, uncoloured midrange and airy treble - often if you want a discrete looking speaker to blend into your room, reduced sound quality is the the price you pay.
Monitor Audio Soundframe have struck a much more acceptable balance between these extremes, producing a stunning sounding hifi speaker which can be hung on a wall like a picture frame, or even let into the wall for a flush finish.
