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. Definitive's 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 the clean and powerful sound.

Minimalist Design, Timeless Appeal       

Powerful minimalist aesthetic with precision-machined components creates a sophisticated look to complement the most distinguished home theater. The sharp lines of the BP9000 Series also echo its precise sonic signature.
