The Benchmark of Center Loudspeakers

For movie lovers looking for total immersion, Reference 4 Meta is the last word in absolute quality. Featuring four bass drivers and 12th generation Uni-Q® driver array with MAT™, this center speaker (can be used as Left-Centre-Right speaker) is a revelation for clarity, detail and emotional depth.

Features

  • 12th Generation Uni-Q Driver Array
  • Dual 165mm (6.5-inch) Hybrid Aluminum Bass Drivers
  • Metamaterial Absorption Technology Absorbs Unwanted Distortion
  • Three-Way Design Optimized for Center Channel Performance
  • Hybrid Aluminum Bass Cone for Tight, Controlled Bass Response
  • Constrained Layer Damping Minimizes Unwanted Vibrations

The Benchmark of Benchmarks

Since 1973, The Reference has continually set the benchmark for loudspeakers and sound reproduction. Pioneering the use of digital technologies to achieve the highest audio accuracy, every pair can be matched within 0.5dB to the laboratory-maintained reference standard.

Always Innovating

Since the first Reference speaker, KEF engineers have continued to innovate using what is possible with The Reference. Ground-breaking in its first incarnation, each subsequent iteration of The Reference has added to the world’s knowledge of the science of acoustics.

Designed, Engineered & Handcrafted in the UK

Since 1961, we have been creating remarkable award-winning loudspeakers at our UK home in Maidstone, Kent. As our flagship HiFi speakers, The Reference is still being designed, engineered, and handcrafted in Maidstone today.
