Premium Surround Sound Systems From Harman Kardon Now Available In The BMW 1 Series, BMW 3 Series And BMW X1
HARMAN, the premium global audio and infotainment group, is pleased to announce that its Harman Kardon Premium sound systems now provide a fascinating all seat surround sound experience in all model variants of the BMW 1 Series, BMW 3 Series and BMW X1. The company's brilliant Logic 7 surround sound system produces crystal-clear treble, a powerful bass and a unique, authentic three-dimensional sound experience. The acoustic experts from the Harman Automotive Division, have been working together with BMW since 1993.
During the early design phase, long before the prototype for a new vehicle model is available, the acoustic experts from Harman Automotive began developing the new Harman Kardon system architecture using a virtual model to determine the precise loudspeakers, amplifier and their specific placement inside each model variant.
Harman Kardon on the BMW X1
Acoustic conditions in the four BMW 1 Series models (Coupé and Convertible), the four BMW 3 Series models (Sedan, Coupé, Convertible and Touring) and SUV BMW X1 couldn't be more different. That's why the speakers have not just been placed in different positions, but also different speaker types have been used depending on the model and body form.
Harman Kardon's Logic 7 technology is the basis for the three-dimensional sound experience providing acoustic integrity and balanced performance. The output of the DSP multi-channel amplifier was tailored by the Harman Acoustic Engineers using the new AuraVox equalizing system. After all, BMW Sedans, Coupés, Convertibles, Tourings and SUV's have dramatically different acoustic conditions.
The Harman-developed AuraVox software and 24 microphones are used in the acoustic tuning of each system, enabling precise measurement and evaluation of acoustic characteristics and performance conditions given unique interiors, loudspeakers, windows and cladding panels. AuraVox uses the extensive measurements to create the appropriate filter for each speaker, correcting signal run-time differences from the various loudspeaker systems to the listener and regulating the volume levels and frequency response patterns of the individual channels. This tuning process is computer-aided. The final process of fine-tuning is performed by trained Harman sound specialists to ensure the overall integrity of each system.
The output of the Harman Kardon DSP amplifier depends on the relevant BMW model: 300 watts in all BMW 1 Series models, 340 watts in the BMW 3 Series Convertible and BMW X1, and 420 watts in the BMW 3 Series Sedan, Coupé and Touring guarantee optimal reproduction of music at any speed or road condition.
The digital signal processor (DSP) of the surround amplifier uses its high computational power to control the frequency responses for all speakers separately according to the values determined, ensuring a well-balanced sound. The result is a perfect spatial listening experience from every seat. The output of the Harman Kardon DSP amplifier depends on the relevant BMW model: 300 watts in all BMW 1 Series models, 340 watts in the BMW 3 Series Convertible and BMW X1, and 420 watts in the BMW 3 Series Sedan, Coupé and Touring guarantee optimal reproduction of music at any speed or road condition.
Harman Acoustic Specialists developed distinct system architectures for all BMW model variants. This includes ten high performance loudspeakers in the BMW 1 Series which include two integrated subwoofers under the front seats delivering low frequency bass impact, while four metal matrix tweeters and four metal matrix mid-range speakers complete the mid and high frequency sound spectrum. The BMW 3 Series Sedan, Coupé, and Touring models have a total of 13 loudspeakers: two integrated subwoofers, four metal matrix tweeters, seven metal matrix mid-range speakers, two of which are located in the rear of Sedan and Coupe, while the Touring version has two integrated EDPL mid-range speakers (EDPL = electro-dynamic planar loudspeaker) in rear headliner. The EDPL loudspeakers are characterized by high dynamism, little distortion and a lightweight design. The most remarkable feature of the extremely low-profile sound transducers is their unique control over the spatial sound. Because of the different body structure, the BMW 3 Series Convertible has two integrated subwoofers, four metal matrix tweeters and five metal matrix mid-range speakers.
The BMW X1 has eleven high-end sound transducers that have been optimally integrated in the vehicle interior. The Metal Matrix Diaphragms of the four tweeters and the four mid-range speakers have a sandwich structure made from both an aluminium core and a ceramic surface producing a top-class, high-fidelity musical experience. The central EDPL loudspeaker is characterised by excellent dynamism, little distortion and a lightweight design. In completion of the Harman Kardon Logic 7 system, two woofers are integrated beneath the driver and front passenger seat delivering a powerful "central bass sound".
