Cadillac will offer its new flagship sedan – the CT6 rear-wheel-drive sedan – with the Bose Panaray system. Cadillac designed this new sound system exclusively for its new model, marking the debut of the latest line of Bose Automotive’s Advanced Technology Series sound systems. This system utilizes the technologies and design elements that are seen in Bose’s home entertainment and professional audio products.
The CT6 cabin will have 34 speakers, with nearly all of them having diameters of less than four inches. Last month in Detroit, General Motors CEO Mary Barra pointed out that this Bose system is a product of the joint development of innovations by the company and its supplier. Barra said that Cadillac has worked with Bose so that the technology can be integrated into the floor.
This system doesn’t need several stand-alone high-fi elements so it’s able to provide “great acoustics and greater efficiency.” In addition, the Bose system features articulated arrays, which are several small speakers positioned in alternating directions. Listeners will appreciate that its setup offers sound at a wider angle, resulting to a sound stage that’s more consistent and broader.
It’s the first time for this design to be used in an automotive system with the dual tweeters placed in the CT6’s A-pillars and rear doors. The line arrays are integrated in the center instrument panel and rear-center console. Since the clusters of small speakers are pointing in the same direction, the sound is focused on the person listening rather than on the reflective surfaces.
The sedan has a center instrument panel that features a group of three 2-inch speakers that are placed in a motorized center-fill enclosure that comes out of the dashboard if the user activates this system. Every corner of the instrument panel has a 4-inch speaker. There are a couple of 2-inch speakers in the rear-center array for sound imaging in the back.
Cadillac and Bose are also proud of the bass. Bose claims that the bass performance doesn’t have any distortion, rattle or unwanted vibration inside the cabin even when the volume is set at the highest level. This was achieved by utilizing several compact high-excursion woofers (which are used in Bose home entertainment systems) and giving them a new bass box design that delivers the low-note output of an enclosure that’s much bigger.
Furthermore, the system comes with two Bose PowerProfile low-frequency enclosures that are exclusively made for the CT6. They are put into the floor under the driver and front passenger seats. The enclosures have a height of 3.5 inches and include four 2.75-inch speakers built side by side and back to back.
This maximizes the distribution of low frequencies, eliminating shaking and buzzing. Included in the system bass sources are a set of 4-inch speakers in each front and rear door – placed in ported enclosures – as well as an upgraded 10-inch high-power Nd woofer installed on the CT6 rear shelf between two 2.5-inch rear-fill speakers.
Marc Mansell, vice president of Bose Automotive Systems Division, said that the Panaray system’s bass performance is “more than heard -- it’s felt.” He also said that just like other Bose products, it’s “not exaggerated or boosted.” What drives this system is a new amplifier platform that has almost twice the processing power of older Bose products.
