Description: * Our Gloss gloss walnut KEF Reference 209 subwoofer is for sale. Call us for more details on the condition and price * Arguably the ultimate home entertainment subwoofer, Model 209 delivers apocalyptic bass extension with minimal distortion even at very high levels.

A lot of air has to be moved to generate bass of this calibre, which is why the enormous 450mm (18in.) cone of the new Model 209 drive unit has a linear excursion of no less than 60mm. This is only possible by combining KEF’s ingenious double suspension system and critically designed large roll surround with a new double radial array of neodymium magnets powerful enough to create a constant 80mm long magnetic field.

Crucially, KEF’s innovative ACE (Acoustic Compliance Enhancement) technology allows the massive resulting bass extension (-3dB at 15Hz) to be realised without a disproportionately large enclosure. By filling the cabinet with activated carbon,ACE almost doubles the effective cabinet volume.

Powering the Model 209 is a 1000W amplifier with Digital Signal Processing equalisation facilities that incorporate six frequency response presets for both line and LFE inputs. There is also a unique system for self-adjusting the output to suit the acoustics of the room using automated measurements of the listening area via the microphone supplied. All DSP facilities together with volume, phase, polarity and crossover parameters are adjustable by remote control.

Finishes/Options: Satin Finishes: Satin Sycamore, Satin Cherry or Satin Walnut: £7,000
