I have seen KEF Ci Series In-Ceiling Speakers at its store and quite satisfied with its sound quality. I am planning to get a pair, but before taking any final decision, so I need userâs view on it. Frankly I have not even heard about it before so need your help to know about kef products. I need to know its quality, durability and longevity. If some user can provide its review it will be great help.
