Skar Audio designed our lineup of elite frequency filters to help maximize the performance and sound quality of your speakers. These easy-to-install frequency filters help reduce audible distortion and prevent damage to your speakers by blocking excessive bass from reaching them.
I got these for TX-35 dash speakers. For most types of music the system already sounded great but I noticed that the dash speakers sounded slightly distorted when I played music with heavy base. These solved the problem.
