iQ70

With all the benefits of the iQ90 in a slimmer enclosure, iQ70 is an assertive full bandwidth two and a half-way bass reflex floorstander that reproduces music and movie soundtracks with equal clarity and flair. With the 165mm (6.5in.) new Uni-Q^® point source array and 19mm (0.75in.) tweeter partnered by a high performance low frequency driver of the same size, it radiates a faultlessly detailed 3D acoustic image evenly throughout the room.

With twin-shrouded terminals for bi-wiring or bi-amplification the iQ70 has impressive power handling, faultless integration, breathtaking vocals and, thanks to the new ‘labyrinth’ internal damping system, heavyweight bass. It has the looks, engineering integrity and acoustic performance to deliver uncompromised listening pleasure with whatever media you choose and is complete with a discreet plinth for greater stability.

Aluminium dome tweeter with ‘tangerine’ waveguide

The unique ‘tangerine’ waveguide delivers a smoother, clearer high frequency response with an even wider dispersion as well as providing an excellent protection from straying fingers.

Uni-Q^®

KEF’s patented Uni-Q driver configuration is what makes the Q Series sound noticeably better than conventional speakers in normal rooms.

The new Uni-Q array in the iQ has been further refined, with a sophisticated new 19mm (0.75in.) elliptical dome tweeter, improved acoustic geometry and ‘tangerine’ waveguide for even more realistic vocals and even smoother, louder and clearer high frequency response.

Enclosures

Inspired by the Reference Series the fully curved enclosures of the iconic Q Series minimise distortion by eliminating internal standing waves. Laminated MDF construction and internal bracing make the cabinets acoustically inert and reduce cabinet colouration. A new internal labyrinth damping system in the floorstanding models eliminate colouration effects from vertical standing waves.

LF Drivers

The new Q Series feature the latest lightweight dual composite LF cones with tall profile rubber surrounds for longer cone throw resulting in increased LF extension and greater power handling. Rigid die-cast aluminium chassis house ultra-low distortion motors incorporating Faraday rings to iron out harmonic distortion.
