The MS 4X-BMW.2 two-way coax-system with vehicle specific baskets and integrated crossover is the perfect sound upgrade for BMW-models with standard OEM speakers without separate tweeters. The system’s 4“ midranges and 20 mm tweeters deliver musical brilliance and authenticity which is usually lacking in original BMW systems. The speakers fit perfectly into the original mounting holes in front- and rear doors of several BMW models.
