Technical Characteristics and Role in the Logic7 System

The Logic7 L7 dashboard speaker operates within an integrated multi-channel system, contributing to an expansive spatial soundstage in BMW vehicles. Its function is to precisely complement the other drivers in the doors and pillars, achieving uniform sound distribution throughout the passenger compartment. The construction has been developed for operation with the factory Logic7 amplifier, ensuring stable operating parameters and predictable performance across the entire frequency range.

Its placement on the left side of the dashboard aids in the proper positioning of sound sources relative to the driver, improving instrument and vocal localization. This allows the audio system to maintain sonic coherence, and the speaker does not require any additional configuration beyond standard factory calibration.
