DETAILS 

The QuickSilver Sport System with Sound Architect™ for the OCTA is the ultimate performance and sound upgrade for this top of line Defender with its 4.4L twin turbo V8.

Loud or Quiet - our system uses our revolutionary Sound Architect™ Module, which is controlled by your mobile phone via our easy to use QuickSilver App. With the valves shut the QuickSilver system provides a civilised note which is unobtrusive and perfect for long journeys and early starts.

Switch to valves open and the monstrous side comes alive with volume and pitch increased to deliver that V8 sound that enriches the experience.

Furthermore, in OCTA driving mode all the pops, crackles and bangs are present on the up-change & overrun, a nice touch.

The QuickSilver system is truly plug & play, it requires no intrusion into the car's OE systems and is completely reversible (on resale?).  


SOUND ARCHITECT

Electronic Valves inc. Sound Architect™ Module - uses QS APP (Android and iOS)

Our Sound Architect App hands control of the valves back to the driver for the ultimate experience. When you select ‘Open’ they’ll stay open and when you select ‘Closed’ they’ll stay closed – this choice will be remembered even after the car’s been turned off and on.

The electronic module included only requires a 12v feed, usually a cigarette-lighter socket. It’s Bluetooth controlled on the driver’s smart device, and pairing takes just a minute.

The electronics are designed in-house and manufactured for us here in the UK, using local British factories.
