Demand Series

Definitive Technology Demand Series 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 mid-bass driver sections, each speaker delivers an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional image for a technically-advanced, premium bookshelf listening experience.

BDSS™ (Balanced Double Surround System) Mid-Bass Drivers

Balanced Inner and outer surrounds on the mid-bass drivers provide greater excursion and output that results in superior mid-range detail and punchier bass compared to drivers of similar size.

Annealed Aluminum Dome Tweeters

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

Laterally Offset Tweeter Assembly

Offsetting the tweeter by 5° delivers better high-frequency dispersion for a more precise center stereo image by eliminating undesirable symmetric diffraction off the corners of the front baffle.

Linear Response Waveguide™

Patented waveguide extends both on and off axis frequency response, while improving dispersion for more detailed mid-range timbre and center image.

20/20 Wave Alignment Lens™

The NEW 20/20 Wave Alignment Lens™ aligns and smooths high-frequencies off the tweeter for improved dispersion and a rich and balanced listening experience anywhere in your room. 

Extruded Aluminum Front Baffle

Clean, modern industrial design provides a timeless look and feel that fits any décor.

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 give you natural, uncolored sound when placed on the speaker, and are easy to remove for your full appreciation.
