Key Features

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.
