Boom! Audio Bass Booster Tour-Pak Port Kit




New product

United States

This Bass Booster Port Kit provides significant improvements in bass response without adding a subwoofer, and has no impact on usable Tour-Pak® carrier cargo capacity. When installed, the open port permits the speaker pod to "breathe", reducing the compression effect that limits speaker cone travel.

  • Hear a 21% increase in bass response for better sound with a fuller bottom end, and an 82% reduction in peak distortion for accurate bass reproduction
  • Noticeable improvement is gained with both Original Equipment and Boom!™ Audio High Performance Speakers
  • Kit contains black-anodized aluminum ports, stainless steel audio-transparent grills, and unique Sound Sealing technology
