Hearing the iQ9 in action takes you to a different place - the illusion of presence is phenomenal. This awesome full size bass reflex floorstander partners the 160mm (6/2") Uni-Q mid/HF array with a brace of potent generation LF drivers featuring ultra-low distortion motors and natural fibre-loaded paper cones. Impeccable vocals, delicious midrange and incredible bass-extension - and with KEF's massive internal bracing, none of the LF distortions that usally affect tall speakers. For orchestral, big band or compositionally intricate works, we're talking devastating accuracy and emotional power. And when complemented by the iQ6c and either iQ3 or iQ7 rear channel speakers, iQ9 is a formidably competent full bandwidth front speaker for large room, high-end home theatre.
