One BMW

Gladen One Line stands for car-specific loudspeaker systems. These are optimally matched to the specific vehicle, both in their design and in their sound tuning.

The challenge was to achieve a perfect interplay of the loudspeaker components under mostly unfavourable loudspeaker installation conditions.

All speakers of the Gladen One Line series were tested and optimally tuned under real conditions in the car, in our in-house test laboratory. At the end of development, all loudspeakers from Gladen have not only undergone numerous parameter and frequency response tests, but have also been fine-tuned by our audio engineers.
