Product Details

KEF Q Series Black Ash Floorstanding Speakers, Model IQ70BK

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 ‘labrynth’ internal damping system, heavyweight bass. It has the looks, engineering integrity and acoustic performance to deliver uncompromised listening pleasure with whatever media you choose. A discreet plinth is also provided 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

  • New horn profile, improves coupling to MF cone
  • Tangerine waveguide for improved dispersion
  • Titanium coated polymer cone
  • Cast aluminium chassis for rigidity
  • Vented design for increased power handling
  • Increased top plate thickness gives greater BL for increased force, control and power handling
  • CCAW edge wound voice coil (copper coated aluminium wire) reduces distortion
  • Blue curve shows the effect of motor improvements giving a more linear and controlled response
  • Faraday rings within the motor system reduce 2nd and 3rd harmonic distortion
  • Combined effect of Faraday rings and CCAW voice coils gives a reduction in 2nd harmonic distortion of 20dB
  • Enhanced LF extension and smoother HF response


  • Fully curved enclosures minimise distortion by eliminating internal standing waves
  • Laminated MDF construction
  • Acoustically inert to reduce colouration
  • Internal bracing and new labyrinth damping system on floorstanding models for reduced distortion
