Demand Series D9 

 

Definitive Technology Demand D9 high-performance bookshelf speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling. Featuring technology advancements to both our aluminum dome tweeter and midrange/woofer sections, each speaker delivers an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for the most technically-advanced, premium bookshelf listening experience. 

 

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.

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

 

Painted Gloss Black 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.

 

Acoustically Transparent Magnetic Grille

The 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.
