R7 gjør seg like godt til film som til musikk. Det låter åpent og presist, med rikelig av detaljer.
Nye R-serien er utstyrt med 12.
generasjon Uni-Q høyttalerelement.
Uni-Q
Placing the tweeter in the acoustic centre of the midrange cone brings
the acoustic ideal of a single point source closer to realisation. The
new R Series benefits from a new 12th generation of the legendary Uni-Q
which has been extensively designed using KEF’s in-house simulation and
analysis tools. KEF’s engineers have been able to dramatically reduce
colouration through reducing resonance in the minute gaps between
Uni-Q’s separate elements. The resulting sound is purer, more precise
and makes stereo imaging far more believable.
