The exhilaration of the drive, the luxurious comforts and the dramatically tuned engine note are not the only onboard entertainment. You also have some exceptional audio system choices. The optional Harman Kardon Premium Sound system offers the most elevated levels of audio refinement, with every component uniquely tailored to perfectly match the Ghibli interior. To achieve this, Harman Kardon sound engineers worked very closely with the development team at Maserati. The core of the system is a state-of-the-art, 900-watt amplifier, delivering rich and detailed sound quality, whatever the source − be it radio, MP3 player, iPhone® or audio streaming device. No fewer than 12 independent channels are deployed, for superb balance within the car environment. A special high-performance subwoofer handles the low-end frequencies, while the mid-range drivers and tweeters ensure that every instrument and every artist can be appreciated in full. 10 high-powered speakers carefully distributed throughout the cabin guarantees sublime sound for all on board the Ghibli.
