Featuring technology advancements to both our aluminum dome tweeter and mid-range/woofer sections, each speaker delivers an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for the most technically-advanced, premium bookshelf listening experience.

 

Bass Port

Bass port in each speaker provides superior low-end extension by smoothly transitioning air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence and distortion.

 

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.

 

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.
