Sold as a \u003cstrong\u003epair\u003c\/strong\u003e, it packs into a relatively compact format the same technology and the same construction philosophy as the floorstanding models in the series: the \u003cstrong\u003etwelfth generation of the Uni-Q® driver with MAT™\u003c\/strong\u003e, a construction carried out entirely by hand in Maidstone, Kent, and a sonic capability that goes well beyond what its dimensions would suggest. It can be paired with the dedicated \u003cstrong\u003eS-RF1 Floor Stand\u003c\/strong\u003e (available separately).\u003c\/p\u003e\n\u003ch2\u003eUni-Q® Gen 12 with MAT™: the perfect point source\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003etwelfth-generation Uni-Q®\u003c\/strong\u003e driver positions the \u003cstrong\u003e25 mm aluminium tweeter with MAT™\u003c\/strong\u003e exactly at the centre of the \u003cstrong\u003e125 mm aluminium midrange\u003c\/strong\u003e, creating a single acoustic point source. The result is remarkably even sound dispersion throughout the room, regardless of the listening position.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eMAT™ (Metamaterial Absorption Technology)\u003c\/strong\u003e technology is a patented acoustic labyrinth capable of absorbing \u003cstrong\u003e99% of the unwanted sound waves\u003c\/strong\u003e coming from the rear of the tweeter, eliminating distortions and colourations at source. The resulting sound has a purity and naturalness that are hard to achieve with any other technology.\u003c\/p\u003e\n\u003ch2\u003eFloorstanding speaker performance in a compact format\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003e165 mm aluminium\u003c\/strong\u003e woofer provides low-frequency extension down to \u003cstrong\u003e30 Hz in-room\u003c\/strong\u003e, with a frequency response that reaches up to \u003cstrong\u003e45 kHz\u003c\/strong\u003e and a maximum sound pressure of \u003cstrong\u003e111 dB\u003c\/strong\u003e. Harmonic distortion remains below \u003cstrong\u003e0.1% between 2 kHz and 20 kHz\u003c\/strong\u003e — a professional-level performance for a bookshelf speaker.\u003c\/p\u003e\n\u003cp\u003eThe crossover frequencies of \u003cstrong\u003e450 Hz and 2.1 kHz\u003c\/strong\u003e ensure a seamless transition between the drivers, with tonal coherence and a three-dimensional soundstage of remarkable precision. As with all models in the series, each pair is measured and matched to within \u003cstrong\u003e0.5 dB\u003c\/strong\u003e of the reference standard maintained in the KEF laboratory.\u003c\/p\u003e\n\u003ch2\u003eConstruction, finishes and integration into the room\u003c\/h2\u003e\n\u003cp\u003eWith dimensions of \u003cstrong\u003e440 × 205 × 422 mm\u003c\/strong\u003e and a weight of \u003cstrong\u003e18.2 kg\u003c\/strong\u003e each, the Reference 1 Meta is compact in its proportions but solid and finished in every detail.
