KEF Ci3120QLM-THX In-Wall Speaker

Product Description

Bring high performance cinematic sound into your room with the KEF Ci3120QLM THX In Wall Speaker, a premium architectural speaker designed for demanding home theater and custom installation applications.

The Ci3120QLM THX combines KEF's advanced 12th Generation Uni Q driver array with Metamaterial Absorption Technology (MAT) and THX Certified Ultra performance. Its compact in wall architecture delivers detailed vocals, precise imaging and powerful sound while allowing the speaker to blend discreetly into the wall.

The Uni Q driver array places the tweeter and midrange driver concentrically, allowing them to operate as a coherent acoustic source. This helps create a wide and consistent soundstage across the listening area, making the speaker particularly useful in dedicated cinema rooms and multi channel home theater systems.

KEF's Metamaterial Absorption Technology helps absorb unwanted high frequency energy from behind the tweeter, resulting in cleaner and more detailed high frequency reproduction.

The Ci3120QLM THX is designed for customers who want the performance of a premium KEF home theater speaker while keeping the room visually clean and free from conventional floorstanding or bookshelf speakers.
