D7

£ 529 pair

The D7 is the smallest of the three models in the Demand Series of loudspeakers from Definitive Technology.
However, it's small size hides an impressive performance from the 4.5" bass/mid driver and the 1" aluminium domed tweeter.

Coupled with the new 20/20 Wave Alignment Lens™, the annealed aluminium dome tweeter delivers smoother high frequency response and improved dispersion for a rich and balanced listening experience. Offsetting the tweeter by 5° delivers a more precise centre stereo image by eliminating undesirable symmetric diffraction off the corners of the front baffle.
A patented Linear Response Waveguide extends both on and off axis frequency response, whilst improving dispersion for more natural mid-range timbre and more precise imaging.

D9

£ 799 pair

The D9 is the middle of the three models in the Demand Series of loudspeakers from Definitive Technology.
The impressive performance from the 5.25" bass/mid driver and the 1" aluminium domed tweeter is further enhanced by the inclusion of a 5" x 9" oval passive bass radiator located in the top of the cabinet, resulting in an extended bass performance for a modest increase in cabinet size.

Coupled with the new 20/20 Wave Alignment Lens™, the annealed aluminium dome tweeter delivers smoother high frequency response and improved dispersion for a rich and balanced listening experience. Offsetting the tweeter by 5° delivers a more precise centre stereo image by eliminating undesirable symmetric diffraction off the corners of the front baffle.
A patented Linear Response Waveguide extends both on and off axis frequency response, whilst improving dispersion for more natural mid-range timbre and more precise imaging. An integrated passive bass radiator in each speaker produces superior low-end extension. Plus, the addition of a larger spider reduces rocking and increases linearity for deep, tight, clean bass response.
