Demand D11

\nDefinitive Technology Demand D11 high-performance bookshelf speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling.

Passive Bass Radiator

\nIntegrated 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. \n

Painted Piano Black Gloss Cabinet

\nEach 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. \n

Annealed Aluminum Dome Tweeter

\nOur annealed aluminum tweeters are precision engineered to articulate nuance and detail in the high-frequency bands for a crystal-clear listening experience \n

Acoustically Transparent Magnetic Grille

\nThe included acoustically transparent magnetic black speaker grilles provide natural, uncolored sound when placed on the speaker, and remove easily when you want to enjoy looking at them fully uncovered. \n

Optional Demand ST1 Speaker Stands

\nThe 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. \n

1" ALUMINUM DOME TWEETER WITH 20/20 WAVE ALIGNMENT LENS™ AND LATERALLY OFFSET TWEETER ASSEMBLY
