The new system uses a combination of high-performance, low-distortion speaker designs, with aluminum tweeters and Kevlar mid-range units. A central speaker with B&W's "tweeter-on-top" technology also features--designed to increase the ratio of direct to reflected sound. In other words, the audio you hear from the speakers is mainly from the speakers themselves, rather than reflected from trim surfaces or the windshield.
Bowers & Wilkins' head of engineering Stuart Nevill describes it as "incredibly tangible and lifelike".
The system comprises a 12-channel Harman amplifier, seven tweeters, seven midrange speakers in two different sizes, four cone woofers and a novel air-ventilated subwoofer. Volvo has designed the XC90 specifically to take account of the subwoofer--it's built into the firm's new Scalable Product Architecture platform. Volvo's head audio honcho Michael Adenauer says it "turns the whole interior space in the car into a giant subwoofer".
Another feature of the audio system allows passengers to tailor the sound for specific seating positions, and even create different acoustic environments--from small music venues to the Gothenbug Concert Hall, home of the Gothenburg Symphony Orchestra. No, really.
Naturally, all of this will be controlled through Volvo's equally new central 'Sensus' touchscreen system, which dominates the car's dashboard. The screen can also access cloud-based functions and works with Apple's iOS CarPlay system--which duplicates the display of occupants' connected Apple devices. The XC90's Bowers & Wilkins audio system will be a top-end option, so it won't be cheap--but if you're an audiophile, it could be well worth the money.
