Sinister Sound gives you the best for your motorcycle, not just empty hype. At Sinister Sound the work has been done. Your system will be heard, loud and clear. Your music will sound full and dynamic at high volumes. Our speaker systems have been designed to play loud with ease, compared to others. This is important for many reasons. Available amplifiers, for the application, limited charging system and competing sounds are just a few of these reasons. Often just two speakers have to get the job done. With this understanding, we tune enclosures when possible, often resulting in more than twice the mid-bass as other systems. Much research and testing has been done to give our customers a speaker system that sounds amazingly clear and powerful.
