Audiophile Performance

Featuring unique technologies such as our Balanced Double Surround System™, linear response waveguide, and laterally offset tweeter assembly, the D11 Large Bookshelf Speakers deliver remarkably smooth, detailed top-shelf audio for true audiophiles.

Aluminum Dome Tweeter
The D11 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, detailed high-frequency performance.

Exclusive BDSS™
The D11’s 6.5” patented Balanced Double Surround System™ (BDSS) woofer provides greater excursion and output for superior midrange detail and punchier bass compared with other drivers of similar size integrated Bass Radiator

Integrated Bass Radiator
The D11 produces superior low-end extension with an integrated 6” x 10” passive bass radiator. Plus, the addition of a larger spider to the radiator reduces rocking and delivers a cleaner, tighter bass response.

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

Meticulous Masterful Sound
True audiophiles are obsessive about all sound, not just their music. Designed with meticulous attention to detail, the D11 also flawlessly reproduces home theater audio.
