The KEF R11 Meta is the flagship floorstanding loudspeaker in KEF’s R Series Meta range, engineered to deliver exceptional clarity, power, and precision for both music and high‑end home theatre systems. At the heart of its design is the 12th‑generation Uni‑Q® driver array paired with Metamaterial Absorption Technology (MAT™), which dramatically reduces unwanted internal resonances and delivers remarkably natural, detailed sound across all frequencies. Four 165 mm hybrid aluminium bass drivers work in harmony to extend deep low frequencies with control, impact, and musicality, allowing the R11 Meta to produce powerful yet refined bass without sounding bloated or muddy. Built with meticulous cabinet engineering and constrained‑layer damping, these speakers minimize distortion and resonance while maintaining structural rigidity. Beautiful finishes such as Black Gloss, White Gloss, and Walnut enhance any listening space, making the R11 Meta both an acoustic and aesthetic centerpiece for serious audio systems.
Features
- 12th‑Gen Uni‑Q® Driver Array with MAT™: Acts as a coherent point‑source for wider dispersion and reduced distortion.
- Metamaterial Absorption Technology: Absorbs 99% of unwanted sound energy behind the tweeter for pure, natural high frequencies.
- Four Hybrid Aluminium Bass Drivers: Provide deep, tight, and controlled bass response.
- Three‑Way Bass Reflex Design: Separate tweeter, midrange, and quad bass drivers for full‑range musical performance.
- Premium Cabinet Engineering: Constrained‑layer damping and rigid build result in reduced vibration and cleaner sound.
- Magnetic Microfibre Grilles: Precision‑cut grilles maintain performance with or without covers.
- Versatile Use: Ideal for high‑fidelity stereo or immersive home theatre setups.
