Powerful L/R Bipolar Speaker Dispersion Pattern

Provides enveloping surround sound, tremendous dynamic range as well as true high-definition sound quality, which results in total sound field immersion.

Aluminum Dome Tweeters

Crystal clear highs bring the most demanding audio to life. Our tweeters play higher in frequency than what is heard by the human ear, creating an authentic reproduction of sound as the artist intends in the studio or concert hall.

 BDSS – Balanced Double Surround System

Improves driver excursion which results in the selected driver producing bass output usually associated with a larger driver, while retaining the improved dispersion and midrange definition of a smaller driver.

 Acoustically Transparent Grille

Enjoy the subtle elegance of the speaker design without having to remove a speaker grille to enjoy natural, uncolored sound.

Totally Inert, Resonance-Free Cabinet

Maximum rigidity with strategically placed bracing improves imaging while reducing resonance, further reinforcing our clean and powerful sound.
