The Demand series from Definitive Technology, an American speaker manufacturer, is crafted to provide a comprehensive, immersive sound experience while maintaining an elegant aesthetic.
The Definitive Technology Demand D11 monitors feature several innovative technical solutions that merit thorough examination. One notable aspect is the unique dual suspension system of the BDSS low-frequency driver, where the polypropylene cone is secured to the basket not just at the outer edge. A secondary suspension in the center connects the inner edge of the cone to the core, which houses the proprietary waveguide. This design enhances the linear movement of the cone, resulting in improved bass and lower midrange performance. Another significant innovation is the Linear Response Waveguide, which, as claimed by the manufacturer, broadens the directivity pattern and enhances the consistency of the frequency response within the speaker’s operational range.
The system is also designed to ensure accurate phase response. The high-frequency driver incorporates an acoustic lens known as the 20/20 Wave Alignment Lens, which enhances sound dispersion uniformity at elevated frequencies. The tweeter dome is constructed from aluminum and is positioned 5 degrees off the central axis, effectively minimizing unwanted symmetrical diffraction at the edges of the front panel. This design significantly enhances the focus of stereo imaging.
The Definitive Technology Demand D11 features a built-in passive bass radiator that extends low-frequency response. Additionally, a larger centering washer contributes to more linear and precise movement, resulting in deep, focused, and clean bass.
At the bottom of the Definitive Technology Demand D11, there are threaded holes for securing the speakers to stands. The acoustic terminals on all monitors facilitate a two-wire connection. The dustproof grille is magnetically attached to the front panel; simply bringing it within approximately one centimeter allows the magnetic field to securely pull the grille into place. The monitor enclosures are meticulously crafted, with the side walls receiving five layers of varnish and polished to a mirror finish, while the front panel is made from extruded aluminum.
The Definitive Technology Demand D11 showcases a front panel crafted from extruded aluminum. Its sleek, contemporary industrial design features a shot-blasted finish, offering a classic aesthetic that enhances any interior. The acoustically transparent magnetic grille ensures pure, uncolored sound and can be easily removed if you prefer the appearance of open speakers. Offered in polished black or white cabinet finishes, each unit is meticulously handcrafted to integrate effortlessly into your environment, with a careful sanding process, five layers of high-quality black lacquer, and a level 6 mirror polish for an exceptional look in your home.
The Definitive Technology Demand D11 speakers provide a transparent and expansive sound with remarkable dynamics. I must highlight the finely tuned bass, which offers ample weight and impact, effectively showcasing both the double bass and the drum set. The midrange is reproduced by the speakers precisely as intended—crisp and open, rich in detail, and delivered with speed and emotion.
