A bespoke audio system needs bespoke music.
The Rolls Royce Phantom's 'Bespoke Audio' system is, literally, the Rolls Royce of audio systems. When the British luxury car maker set about developing the new Phantom, every detail was scrutinized with the aim of perfection. When it comes to the audio setup, Rolls Royce has provided some detail into how it approached designing and building the sound system. The automaker even answered a question nobody really expected an answer to: What does the playlist the audio engineers use to test and develop the system look like? We'll get to that, but the short answer is: varied.
Configuring an audio system for a car is much more complicated than designing one for a house. There are different surfaces in the confined space of a car that will both reflect and dampen sound, and that's before taking into consideration external noises bleeding through such as tire, wind, and engine noise. Admittedly, Rollers tend to have a remarkably quiet noise, but silence is, currently, impossible to achieve inside a moving vehicle. Taking all that into account, Rolls Royce put together the interior design in tandem with the audio development in order to get as close to perfection as possible. The level the engineers went to for quality is close to insane and started by using a recording studio's playback room as a benchmark.
The system itself uses an 18 channel amplifier. That's a channel for each speaker, and each speaker is built using magnesium-ceramic compound speaker cones to maximize frequency response. Rolls Royce boasts that: "The Bespoke Audio system makes the most of the highest quality, uncompressed dynamic rate music providing an exceptional listening experience." And to get that level of precision, the system was tuned using the finest audio detection units in the world: The MK 1 Human Ear Drum. To help refine the sound, the engineers used a playlist for testing curated by the company's audio engineers.
The playlist includes tracks many will nod there head at in understanding, such as Pink Floyd's Wish You Were Here and Paranoid Android by Radiohead, Hotel California by The Eagles, Sad But True by Metallica, some Rage Against The machine tracks. However, the full list is as broad as it is long and covers everything from a classic British dance anthem to solo tracks from legendary drummers and bass players.
