DEFINITIVE TECHNOLOGY D15 High-Performance Tower Speaker

Room-filling Sonic Performance

Lose Yourself In Sound The D15 tower speaker features an exclusive 3-way driver configuration with a 1” annealed aluminum dome tweeter, a 5.25” BDSS™ midrange woofer, and dual 5.25” carbon fiber bass drivers, complemented by dual 8” side-firing passive radiators, for a full-range, room-filling sonic performance.

Proprietary Drivers

Detailed, balanced audio Definitive Technology designed the drivers in the Demand Series to deliver a perfectly balanced, precise, musical sound.

Clear, Precise Highs The D15 couples a laterally offset 1" Aluminum Dome Tweeter with our 20/20 Wave Alignment Lens. We offset the tweeters by 5 degrees, minimizing wave cancellations off the front baffle to deliver a more precise center stereo image and ensure clear, detailed high-frequency performance.

Dual 8" Passive Bass Radiators

For visceral bass response Twin integrated 8” passive bass radiators in each speaker produce superior low-end extension for highly controlled, highly impactful bass.

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, precise imaging Our patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.
