Overview

The flagship speaker of KEF's Reference Series, the Reference 5 Meta is designed, engineered, and handcrafted in Maidstone, Kent UK.

KEF's 12th generation Uni-Q® driver array with MAT™ is housed in a cabinet with constrained layer damping, providing extremely high fidelity and a largely colourless output, making changes to, and quality of, amplification, sources and source material immediately obvious.

Rear porting allows for down to 40Hz bass output, but the design is well executed, remaining tight and detailed at lower frequencies. 

Each speaker is measured by a laboratory-maintained reference standard to ensure pairs are matched within 0.5dB.
