About:The smallest model in the 600 series is an incredibly versatile loudspeaker. It is an ideal bookshelf speaker for stereo in smaller rooms, but also a refined rear speaker in home theatre systems.The CM1 may be ideal for smaller spaces, but don’t let the size of this bookshelf speaker fool you. Thanks to the quality of its construction, it’s capable of producing a sound that’s a match for its bigger brothers.On a bookshelf or a speaker stand, the CM5 will give you a wonderfully big, expansive sound even if you don’t have the floorspace to match
