I sat in a pre-production US-spec iX (it had a VIN) yesterday when I happened to be at the BMW store. A guy from BMW NA had brought it to the dealer for their staff to look at.i didn't realize that the iX is going to be the first EV to use Bowers & Wilkins’ Diamond Dome tweeters! The sound is going to be nuts.
The new BMW iX will be the first fully electric vehicle to use Bowers & Wilkins’ Diamond Dome tweeters for near-perfect sound. The speakers are the latest step in BMW and Bowers & Wilkins’ longstanding relationship.
The companies will continue to work together into the future to deliver what they claim is the most advanced sound system found in a car. The aim, says Bowers & Wilkins, is to create an experience that makes it sound like you’re in the recording studio with the artist you’re listening to.
To achieve that, the BMW iX features three Aluminum Dome tweeters, five Aramid Fiber midrange speakers mounted as high as possible within the cabin, and two Diamond Dome tweeters. Those last tweeters do actually use diamonds in their construction because of the material’s rigidity.
By flexing as little as possible, the diamond domes impart little to none of their own character on the sound that is being created, resulting in clear audio. They also feature “Nautilus swirls,” or spiraling channels behind the tweeter domes that dissipate reflected sound waves emanating from the rear of the drive unit to limit distortion.
Another eight speakers are integrated into both the front and the rear headrests, which can be individually adjusted for a personalized audio experience. Giving the whole experience a bass-full foundation are the four bass speakers and the 4D Shakers that are strategically placed through the cabin, a first in the automotive world.
The Bowers & Wilkins 800 Series loudspeakers that are going into the BMW iX are the same found at Abbey Road Studios. In keeping with the minimalist interior of the EV, though, the tweeters are covered in brushed stainless-steel covers with a laser-etched logo and a discreet lighting effect.
Under the hood, so to speak, the iX will have three motors that combine to produce 516 hp and 564 lb-ft (764 Nm) of torque and are powered by a 106.3 kWh battery pack and it’s set to hit U.S. showrooms in the first quarter of 2022.
