Proprietary Drivers
for clean, detailed, balanced audio
Definitive Technology designed the drivers in the Demand Series to deliver a perfectly balanced, precise, musical sound.
Clear, Precise Highs
The D17 couples a laterally offset 1” Aluminum Dome Tweeter with our 20/20 Wave Alignment Lens™. We offset the tweeters by 5°, minimizing wave cancellations off the front baffle to deliver a more precise center stereo image and ensure clear, exacting high-frequency performance and detailed soundstage.
Dual 10" Passive Bass Radiators
for visceral bass response
Twin integrated 10” passive bass radiators in each speaker produce extraordinary low-end extension for louder, lower, unforgettably clean bass performance.
Audiophile-Quality Crossovers
for beautifully balanced audio
Demand Series crossovers are built with the latest premium audiophile-quality parts, including polypropylene metal-film capacitors and air-core inductors. These high-end components meticulously manage frequencies for clean and crystalline treble, refined and articulate midrange, and linear, low-distortion bass. This ensures that every detail comes through within a clear, balanced presentation that never sacrifices power.
Linear Response Waveguide™
for natural imaging
Our patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.
Masterful Movie Sound
Flawless Home Cinema Audio
True audio enthusiasts are obsessive about all sound, not just their music. The meticulous attention to detail that enables the D17 Tower Speaker to beautifully reproduce music also enables it to flawlessly reproduce home theater audio.
Artistry to the
eye and ear
Extruded aluminum front baffles capture a clean, modern aesthetic with a bead-blasted finish for a timeless look and feel to fit any décor.
Each speaker is meticulously sanded and painted with five layers of premium gloss paint, then buffed to a near-mirror finish.
