The new technology - dubbed AcoustiVision - uses a vehicle's standard rear glass to create an in-car subwoofer. The Magna system uses two exciters at the base of the window, which are fed via a trunk-mount amplifier that boosts the stereo signal from 12 volts to 200. Once the system is connected, the rear glass acts as the membrane of the speaker.
Although futuristic sounding, the technology could have a real place in the automotive world. AcoustiVision can cut vehicle weight since it eliminates the need for a bulky subwoofer and the system consumes less energy than a conventional speaker. I's clever packaging can also be fit to virtually any vehicle.
Magna has yet to land a big contract for the technology, but the company says AcoustiVision could be ready for production in 2015.
