The Frelander II is the first vehicle in the world to utilise Dolby's surround sound standard
Land Rover's latest car, the all-new Freelander II, will be the first-ever automotive application of Dolby Pro Logic II 7.1 surround sound technology, developed specifically for the unique listening environment of the car. The technology, developed by Alpine, is generally seen in high-end home theatre and entertainment systems and completely immerses its occupants in a sound experience that is all-enveloping. Alpine has created a new 440-watt amplifier to effortlessly power the system. Using the very latest surround sound technology, the system employs a multichannel amplifier in 7.1 mode. The comprehensive 14-speaker system has been specifically designed and the three-way front speaker layout of mid, bass and tweeter together with the centre speaker replicates the sound stage right in front of the occupants. Tweeters and bass drivers in the rear doors and, for that true surround experience, rear fill speakers in the pillars, deliver enveloping sound through the entire cabin. Deep, low down power can be relied upon from a twin-channel, powered 80-watt subwoofer. Rear passengers also get two headphone sockets, which allow them to listen to a different music source. Dolby Pro Logic II 7.1 technology works by processing any stereo (two-channel) audio into seven playback channels of surround sound plus a subwoofer channel for low frequency sounds. By detecting the directional cues that occur naturally in stereo content, Dolby uses these elements to create a surround sound playback experience. The technology has been developed specifically to suit the unique acoustic environment of a vehicle, enabling all passengers to experience the enveloping and exciting audio regardless of their position within the car.This first branded Alpine system is the latest partnership between the audio specialist and vehicle manufacturer. Ever since the Discovery II and 1998 Range Rover, Alpine has worked closely with Land Rover to produce infotainment products that perform as effectively as the car, irrespective of the terrain. Truly understanding the tougher environment a Land Rover thrives in it has gone ahead and permitted Alpine to create their first branded sound system for the Freelander II.
Powered directly by the amplifier, the 2 Ohm, 100mm centre fill provides the surround experience for front occupants. As the name suggests the speaker fills the void between front occupants, enhancing the impression of the concert being played out right in front of you. Responsiveness is assured through the use of lightweight neodymium magnet materials. Lightweight materials on the dashboard have the added advantage of lowering the centre of gravity, significant for an SUV.
Neodymium tweeters are used to increase responsiveness. Ideally located in the front and rear doors the tweeters ensure faithful reproduction of the higher frequencies. Highly specified, the 4 Ohm units are fitted in both the front and rear of the cabin ensuring audio excellence wherever seated.
For faithful reproduction of lower frequencies, a powerful and substantial bass unit was developed. Fed by separate 40 watt audio channels, these units have the ability to move large volumes of air. With a distinct mid unit in the premium system, the bass unit can be tuned to focus purely on deep, crisp and accurate bass reproduction.
For more accurate mid range reproduction, the Freelander II has new mid range speakers. With most of what we hear being in this range, the performance of this speaker is critical. With rapid response, the mid speaker can perform in harmony with the mid bass and tweeter arrangement.
The substantial subwoofer is driven by two 40 watt amplifier channels to accurately reproduce the lowest frequencies. A substantial ferrite magnet system is used to move the air that creates not only the sound but the deep feeling. Strong and light, the enclosure has been designed specifically for the Freelander II creating an environment that permits Alpine's audio engineers to tune the system for the best bass response across the range.
For the true surround sound experience, the new Freelander II has a further two mid units in the rear of the vehicle. Providing scale and depth to performances, they are ideally suited for concert or live music reproduction.
