Retrofitting speakers for many BMW and Mini models at an affordable price? And in very good quality? The SIGNUM SXB speaker systems prove that this does not have to be a contradiction . If the original factory system simply seems too thin for you, these models are the right choice. Brilliant highs, balanced mids and powerful bass are worth it.

Everyone knows that it is not easy to install good speakers in BMW vehicles. For this reason, ESX has developed all the components to make this "hurdle" easier to overcome. Thanks to a consistent plug and play implementation, it is quite easy to replace the original speakers without any problems. All connectors, screws and the speakers themselves fit perfectly.
