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.

I'm still in construction, but these sound amazing

I'm currently building a 16X20 theater room in the basement. I'm building to the Dolby Atmos standard. For speakers in a well above average cost, but not audiophile, they're in a sweet spot. Nice design too. I bought a complete 5.2.4, but wired for 7.2.4, Definitive Technology speaker system. It consists of: 9040 towers, 9040 CS Center, 9080 SR surrounds and 6.5 circular heights. When the components arrived I simply threw up my Denon 3700, the towers and center, not even remotely positioned and they ROCK. The bass was particularly tight! By the way Denon and Definitive are part of a company called Sound United who is also the parent company to Polk and Marantz. I'm hoping to have my room done by January 10!
