Definitive Technology Demand D 15 Stand-Speaker

PLEASE NOTE! With these speakers, there is a left and a right box! Please order each page to receive a pair!

The Demand D15 tower speakers deliver full-range, room-filling sound and precise imaging from a modern, minimalistic design. Fill larger rooms with detailed Hi-Fi or home theatre sound with extended, controlled bass, large dynamics and a wide, precise soundstage. The Demand Series outperforms the competition in its price-class with more performance in a smaller form factor, thanks to exclusive technologies as a laterally offset 1” annealed Aluminium dome tweeter, BDSS™ midrange/woofer sections, new carbon fiber woofers and dual side-firing passive radiators. Demand more from your Hi-Fi and home theatre experience.

Overview

• D15 high-performance, 3-way tower speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling
• Dual integrated side-firing passive radiators produce extended low-frequency reproduction free of port noise, from a smaller enclosure design
• 5.25” BDSS™ drivers provide greater excursion and output that results in superior mid-range detail compared to drivers of similar size
• 1” annealed Aluminium dome tweeter with 20/20 Wave Alignment Lens™ delivers accurate, smooth highs, a wider sound stage and precise imaging
• Laterally offset tweeter assembly: Reduces unwanted diffraction for a more precise centre image in music reproduction

EXTENDED BASS PERFORMANCE WITH DUAL PASSIVE RADIATORS

The Demand D15 tower speakers feature an exclusive 3-way driver configuration with a 1” annealed Aluminium dome tweeter, a 5.25” BDSS™ midrange woofer, a dual 5.25” carbon fiber bass driver complement with a dual 8” side firing passive radiator configuration for a full range, room-filling sonic performance. The sophisticated and elaborate bipolar passive radiator design produces extended low-frequency reproduction free of port noise, from a smaller enclosure design.

WIDE AND PRECISE SOUND STAGE - WITH LATERALLY OFFSET ALUMINIUM DOME TWEETER AND WAVE ALIGNMENT LENS

Proper tweeters must excel in three ways: they must be stiff, light, and well-damped in order to minimize their material characteristics that will affect high-frequency reproduction. Aluminium is naturally stiff and lightweight, meeting the first two requirements. To achieve the third, Definitive Technology tweeters undergo an annealing (heat treating) process to shape and soften the material, thereby providing the necessary material damping. On top of that, silk surrounds further add soft-dome benefits.

The Aluminium dome tweeters deliver a clear, precise high frequency response and the 20/20 Wave Alignment Lens™ smooths high frequencies off the tweeter for improved dispersion and a rich and balanced listening experience anywhere in your room.
 
A unique sonic signature feature of the Demand Series, the tweeter is offset to deliver a more precise center stereo image and eliminate undesirable symmetric diffraction off the corners of the front baffle.

LARGE DYNAMICS FROM BDSS™ MID-RANGE - BALANCED DOUBLE SURROUND SYSTEM

Our patented Double Surround mid-range driver provides greater linear excursion and output that results in superior mid-range detail compared to drivers of similar size. 

IMPROVED DISPERSION WITH 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. 

NEWLY DESIGNED CARBON FIBER WOOFERS

This new addition to the sonic signature of the Demand Series tower features a dedicated woofer section for low frequency reproduction. Carbon fiber offers greater rigidity to the cone for deeper bass notes, while preventing cone distortion that can occur with other less rigid materials. Carbon fiber is a strong but light material, ideal for sound reproduction. It ensures that the woofers are sturdy yet light, able to handle higher excursion without deforming and provides deeper, clean low frequency.

EXTRUDED ALUMINIUM FRONT BAFFLE

Clean, beautiful modern industrial design with an extruded Aluminium front baffle bead blasted finish that provides a timeless look and feel that fits any décor. Lightweight, durable and recyclable, Aluminium is truly the metal of a modern lifestyle.

5-layer painted high-gloss black cabinet

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

Acoustically Transparent Magnetic Grille

Grilles can be removed easily when you want to enjoy looking at them fully uncovered while ensuring natural, uncolored sound when placed on the speaker
