Volvo XC90 Audio System Features Bowers & Wilkins Tweeter-on-Top Technology

Bowers & Wilkins teams up with Volvo Car Group for the Volvo XC90 audio system.


Bowers & Wilkins has teamed up with Volvo Car Group for the 2015 Volvo XC90 audio system. It is Bowers & Wilkins first audio system built into a luxury SUV, while the Volvo XC90 is world’s first in-car system to implement Bowers & Wilkins tweeter-on-top technology.

The tweeters utilize technology from Bowers & Wilkins Nautilus speakers, including spiraling diffusion channels that soak up reflected sound and reduce resonance. The Volvo XC90 features 19 speakers driven by a Class D amplifier, delivering a total of 1,400 Watts power. Each speaker matches the interior acoustics of the car.

“With tweeter-on-top technology, more of the signal reaches the listener directly from the tweeter,” says Stuart Nevill, Bowers & Wilkins Head of Engineering. “So the XC90 system sounds incredibly tangible and lifelike.”

  • 4 x 25mm Nautilus tweeters (front & rear doors)
