Product Details

KEF Q Series Black Ash Bookshelf Speakers, Model IQ30BK

The iQ30 is an incredibly versatile music or home entertainment speaker with a seductive lightness of touch. With the same curved cabinet design minimising internal reflections, it has a lyricism and depth not normally associated with bookshelf speakers. It delivers an excellent dynamic expression with a bass response that is deep and expansive. The latest generation 160mm (6 1/2in) Uni-Q array and new ‘tangerine’ waveguide gives a dispersion that is characteristically consistent, so you enjoy the same extraordinary illusion of presence wherever you sit. It’s like re-experiencing your favourite tracks or movies for the very first time. As easy to position as they are to drive, the new iQ bookshelf models are magnetically shielded like the rest of the range.

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
