KEF Q Concerto Meta Passive Hi-Fi Bookshelf Speakers (Pair), Black | Premium Hi-Fi Passive Bookshelf Speakers | Versatile Home Theatre System | 3-Way Bass Reflex | For Music, Gaming, TV & Movies

PREMIUM HI-FI SOUND, MADE EASY TO HEAR: Experience music and movies with greater clarity, depth and realism from the KEF Q Concerto Meta. Designed for listeners who want to hear more detail, richer bass and a more convincing soundstage than typical budget bookshelf speakers.
SOUND THAT FILLS THE ROOM: KEF's 12th Generation Uni-Q places the tweeter at the acoustic center of the midrange driver, creating a more coherent sound from a single acoustic point. The result is detailed, natural audio with exceptionally even dispersion, so more of the room can enjoy the same immersive sound, not just the person sitting in the “sweet spot”.
CLEANER, MORE NATURAL SOUND: Metamaterial Absorption Technology absorbs 99% of unwanted sound from the rear of the tweeter, reducing distortion before it reaches your ears. This KEF-developed technology helps deliver cleaner high frequencies and a more natural, effortless presentation.
TRUE 3-WAY DESIGN WITH POWERFUL BASS: Unlike many compact bookshelf speakers, Q Concerto Meta uses dedicated high, mid and low frequency drivers. A 6.5-inch hybrid aluminum bass driver delivers deep, controlled bass, while dedicated midrange and tweeter drivers preserve vocal clarity and fine detail, giving music and movies greater scale, impact and realism.
BUILD A HI-FI SYSTEM THAT GROWS WITH YOU: Q Concerto Meta is a passive bookshelf speaker designed to work with a separate amplifier, giving you the freedom to choose the amplification that best suits your system. Start with a high-quality stereo setup and upgrade your amplifier or add further speakers for home theater as your needs evolve, without replacing the speakers themselves.
