KEF Ci9000ACE in-wall speaker

 The in-wall Ci Series 9000ACE from KEF is a innovative new advance into custom installed loudspeakers. The 165mm (6.5in.) Uni-Q® driver array brings out the full emotional depth and texture of vocals, whether sung, shouted, spoken or whispered - hardly surprising, since it’s exactly the same unit as you’ll find on the XQ series. On either side, a matching pair of long throw bass drivers with ultra-low distortion motors for low frequency response that’s as lucid as it is gutsy - and thanks to KEF’s Acoustic Compliance Enhancement technology, (ACE) what you actually hear is a level of bass extension that’s normally only obtainable with much larger speakers.

Ci Series 9000ACE comes with two grille options: The pictured black cloth covered grille and a white overhanging grille. A grille for painting or covering is also available.

The new Ci Series 9000ACE.
More range, more depth. More alive.
