The D9 is the intermediate model in the Demand series by Definitive technology. They are a high performance design offering great detail without becoming harsh and agressive and use an ABR(Auxiliary Bass Radiator) rather than a bass port.

Definitive Technology Demand D9 high-performance stand mount speakers deliver full-range, room-filling sound and precise imaging in a modern, elegantly styled and compact cabinet.

Definitive Technology’s patented BDSS double surround midrange/woofer provides greater excursion and output that results in superior mid-range detail and punchier bass compared to drivers of a similar size. The D9 uses a 5.25 inch woofer and a 1 inch Aluminium dome tweeter, that has been offset by 5° to deliver a more precise centre stereo image by eliminating undesirable symmetric diffraction caused by the corners of the front baffle. The D9 also makes use of an ABR(Auxiliary Bass Radiator) rather than a bass port making positioning in your room potentially easier with regards to avoiding bass "boom"

The Demand series features technology advancements to both their aluminium dome tweeter and mid-range/woofer sections so each speaker delivers an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for the most technically-advanced, premium bookshelf listening experience.

The D9's are available in both black and white high gloss finishes.
