Demand Series Large High-Performance Bookshelf Speakers

Definitive Technology Demand D11 high-performance bookshelf speakers deliver full-range, room-filling sound, and precise imaging in a modern, elegant styling. Featuring technology advancements to both our aluminium dome tweeter and midrange/woofer sections, each speaker delivers an unrivalled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for the most technically advanced, premium bookshelf listening experience.

1" ALUMINUM DOME TWEETER WITH 20/20 WAVE ALIGNMENT LENS™ AND LATERALLY OFFSET TWEETER ASSEMBLY
Coupled with our new 20/20 Wave Alignment Lens™, our 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. 

LINEAR RESPONSE WAVEGUIDE™
Patented Linear Response Waveguide extends both on and off axis frequency response, while improving dispersion for more natural mid-range timbre and more precise imaging. 

BDSS™ MIDRANGE/WOOFER
Patented Balanced Double Surround System (BDSS) midrange/woofer provides greater excursion and output that results in superior mid-range detail and punchier bass compared to drivers of similar size.

Passive Bass Radiator
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.

Painted Piano Black Gloss Cabinet
Each cabinet is hand-crafted to blend seamlessly with your lifestyle—meticulously sanded, painted with five layers of premium black gloss paint, then buffed for a near-mirror finish (Level 6) for an uncompromising look in your home.

Optional Demand ST1 Speaker Stands
The optional ST1 speaker stands (sold separately) elevate the speaker to the ideal listening height (32”) and can be filled with your choice material (ex. sand) to provide a solid and stable speaker foundation.
