Get to know this product.

1" Aluminum Dome Tweeter

Coupled with our new 20/20 Wave Alignment Lens™, our annealed aluminum dome tweeter delivers smoother high frequency response and improved dispersion for a rich and balanced listening experience. Offsetting the tweeter by 5° delivers a more precise center stereo image by eliminating undesirable symmetric diffraction off the corners of the front baffle.

Extruded Aluminum Front Baffle

Clean, modern industrial design with a bead blasted finish provides a timeless look and feel that fits any décor.

Linear Response Waveguide™

Patented Linear Response Waveguide extends both on and off axis frequency response, while improving dispersion for more natural mid-range timbre and more precise imaging.

BDSS™ Midrange/Woofer

Patented Balanced Double Surround System (BDSS) midrange/woofer provides greater excursion and output that results in superior mid-range detail and punchier bass compared to drivers of similar size.

Passive Bass Radiator

Integrated passive bass radiator in each speaker produces superior low-end extension. Plus, the addition of a larger spider reduces rocking and increases linearity for deep, tight, clean bass response.

Annealed Aluminum Dome Tweeter

Our annealed aluminum tweeters are precision engineered to articulate nuance and detail in the high-frequency bands for a crystal-clear listening experience.

Painted Gloss Black Cabinet

Each cabinet is hand-crafted to blend seamlessly with your lifestyle—meticulously sanded, painted with five layers of premium black gloss paint, then buffed for a near-mirror finish (Level 6) for an uncompromising look in your home.

Acoustically Transparent Magnetic Grille

The included acoustically transparent magnetic black speaker grilles provide natural, uncolored sound when placed on the speaker, and remove easily when you want to enjoy looking at them fully uncovered.

Optional Demand ST1 Speaker Stands

The optional ST1 speaker stands (sold separately) elevate the speaker to the ideal listening height (32”) and can be filled with your choice material (ex. sand) to provide a solid and stable speaker foundation.
