Description

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.

Superior Midrange Detail

The D17’s 6.5” patented Balanced Double Surround System™ (BDSS) mid/bass driver provides greater excursion and output for superior midrange detail and punchier bass compared with other drivers of similar size.

Deeper, Cleaner Bass

The D17’s custom-woven 6.5” carbon fiber woofer produces superior cone rigidity for deep, evenly extended bass notes while preventing distortion-causing cone deformation that can occur with less rigid materials.

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.
