New 2020 Corvette C8 Has The Loudest Bose Audio System In A Two Seat Coupe
260Bose announces its most powerful and highest performing sound system ever for a sports car with the debut of the Bose Performance Series system in the eighth-generation Chevrolet Corvette.
The all-new 14-speaker Bose Performance system in the 2020 Corvette Stingray sets a new standard for sports car sound with highly advanced signal processing and tuning that delivers the loudest — yet clearest — Bose audio experience ever in a two-seat coupe cabin. And it continues a tradition of collaboration between Bose and Chevrolet that began with the 1984 fourth-generation Corvette.
“The new Corvette Stingray is phenomenal, and it delivers a special kind of experience that doesn’t happen very often. So, getting every detail just right is critically important — and that includes audio,” said Tobe Barksdale, chief audio engineer, Bose Automotive Systems. “The next-generation Corvette already delivers a thrilling soundtrack, courtesy of the engine. And when it comes to adding music to the mix, the custom-engineered Bose Performance Series system brings the moving emotion you’d expect in a legendary vehicle like this.”
Engineering a World-Class Sound System
Bose engineers worked closely with Chevrolet to develop the sound system during the most significant transformation in Corvette’s storied history, as it moves to a mid-engine design from the more conventional front-engine layout.
Shifting the engine location changes the size and shape of the vehicle cabin compared to previous generations and impacts the way music and sound is heard inside the car. This presented new challenges to the Bose system engineers, requiring innovative and creative techniques to deliver the best listening experience possible. Using a deep understanding of psychoacoustics — the study of how we perceive sound — along with advanced tuning capabilities, the Bose team designed an offering unlike any other in more than 35 years of engineering sound systems for Corvettes.
“From the beginning, we knew we had to have an audio system that carefully balanced the need to isolate the occupants from the engine compartment in the rear, while providing live performance-like audio clarity,” said Tadge Juechter, Corvette executive chief engineer. “The Bose system technology in the 2020 Chevrolet Corvette Stingray delivers that careful balance.”
With 14 precisely placed speakers inside the cabin — the most Bose has ever put into a two-seater — each occupant is surrounded by a diverse mix of high-quality and lightweight loudspeakers.
Across the instrument panel, 2.5-inch and 3.25-inch neodymium Bose Twiddler speakers help establish a broad and spacious sound stage, along with a combination of 4-inch neodymium wide-range speakers and 1-inch neodymium tweeters in each upper door. A pair of 5.25-inch neodymium wide-range speakers and three additional 3.25-inch neodymium Twiddler speakers in the rear of the cabin deliver rich, immersive sound. Deep, impactful bass performance is provided by 10-inch Bose Nd woofers creatively integrated in each door.
Discreetly Packaged Bass Performance
The Bose Nd woofers aren’t visible, but they produce a tremendous amount of low-frequency output, with minimal distortion, by using the architecture of the door itself as a massive bass enclosure. Unlike conventional systems that use a customized bass box with woofers inside, space limitations in the new Corvette made that approach impractical.
And instead of placing speaker grilles over the woofers, which could be abrasive to the driver’s and passenger’s legs when cornering the vehicle at high speeds, Chevrolet designed a smooth, padded surface for the interior door panel.
