EXPLORE A NEW DIMENSION OF SOUND The BP9040 tower speaker is your answer for remarkable, immersive, room-filling sound so you can experience every detail of pure home theater. Forward Focused Bipolar Array expands your room’s entire soundstage. Aluminum dome tweeters, high-performance drivers, integrated powered subwoofer and Intelligent Bass Control let you hear and feel every note as the artist intends. Dolby Atmos / DTS:X compatibility let you explore true multi-dimensional sound. Timeless, minimalist design. This is what obsession sounds like. 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. Cast Aluminum Base with Spikes and Floor Glides The wide footprint increases overall stability of the tower speaker, while the addition of spikes or floor glides help keep your speakers firmly in place whether on carpet or other solid floor surfaces like hardwood or cement. LED Backlit Definitive Technology Logo To highlight the integrated powered subwoofer and show that your speaker is receiving a signal, we’ve added an LED logo at its bottom front panel. Turn it on or off at your leisure and also note that it will automatically turn off/standby after 20 minutes of no active signal.
