Superior Details

Finely Balanced

Featuring unique technologies such as our Balanced Double Surround System, linear response waveguide, and laterally offset tweeter assembly, the D9 Mid-Sized Bookshelf Loudpeakers deliver top-shelf, balanced audio for any application.

8” Aluminum Dome Tweeter
for clear, precise highs

The D9 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 D9’s 5.25” patented Balanced Double Surround System™ (BDSS) mid/bass driver provides greater excursion and output for superior midrange detail and smoother bass compared with other drivers of similar size.

Integrated Bass Radiator
for superior low-end extension

The D9 produces superior low-end extension with an integrated 5” x 9” passive bass radiator. Plus, the addition of a larger spider to the radiator reduces rocking and delivers cleaner, tighter bass response.

Audiophile-Quality Crossovers
for balance and power

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.
