Definitive, the top-selling American premium loudspeaker brand, has launched a trio of bookshelf speakers designed to delight even the most demanding music-lover.

The Definitive Demand speakers are designed to deliver a precise stereo image over a wider listening area. Additionally, the company tell us that they have a more natural midrange and surprising bass power from their compact enclosures - the entry-level D7 is less than 25cm tall.

As part of Definitive Technology's policy of global design thinking, the Demand Series speakers have been tuned by experts from the company's in-house acoustics specialist teams in Europe and North America. At the heart of the Demand Series is its unique choice of drive units: the treble driver is offset by 5° to eliminate symmetrical diffusion from the corners of the baffle, thus enhancing stereo imaging. Additionally, the new 20/20 Wave Alignment Lens smoothes the off-axis response of the tweeter for improved dispersion over a wider listening area.

The same thinking informs the Linear Response Waveguide used on the mid/bass drivers improving both on- and off-axis frequency response and improves dispersion. Furthermore, the same BDSS Double Surround woofer technology found in the company's impressive BP9000 Series allows longer driver excursions while retaining precise movement, for greater bass punch and control.

A passive bass radiator is used to tune the low frequencies in the larger D9 and D11 models, while the smallest Demand Series speaker, the D7 users a reflex port.

The drivers are mounted in an inert three-layer front baffle using extruded aluminium, while the cabinets are finished in five layers of black gloss paint, and polished to a mirror finish. The Demand Series features both wall-mounts and a locking system to fix the speakers to the optional ST1 stands.
