DEFINITIVE TECHNOLOGY D17 Flagship Tower Loudspeaker

Flagship Performance

Breathtaking Musicality 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.

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 8” 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.
