Definitive Technologies Demand series D17 Floorstanding Speakers

D17 tower speakers are meticulously engineered with a laterally offset 1” annealed aluminum dome tweeter, a 6.5” BDSS™ midrange woofer, and dual 6.5” carbon fiber bass woofers complemented by dual 10” side-firing passive radiators for a full-range, breathtakingly musical sonic performance.

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.
