Limited Storage Unlimited Bass

The Flatline Series was designed for vehicles with limited storage space like regular cab trucks, small cars and convertibles. You can mount it almost anywhere – it can fit under the rear seat of a truck or behind. F Series sub doesn’t have a vented port so it won’t take up all of your space and it will give you a lot of mounting options. Although, it’s one of the smallest and thinnest enclosures we’ve built, it still delivers a huge bass impact. For the money/space/bass balance, this might be the best option for your need.

The Flatline Series subwoofers feature:

  • Interwoven Into Spider Tinsel leads

  • Durable Butyl Rubber Surround

  • Injection Molded Polypropylene Cone

  • Unique Fin Shaped Heatsink

  • 2" Copper Voice Coil

  • Steel Basket

  • Ferrite Magnet

  • Kapton Former Material

The Flatline Series ensures a smooth clean, yet huge bass impact in smaller, tighter spaces.

Hassle-Free Connection

The wire terminal is one of the most important features of the sub which handles the power transfer from your amp to the sub. Cheap outdated spade terminals take more time and effort to install and to keep it connected once installed. All Harmony Audio subs feature a spring-loaded push terminal that will accept direct speaker wire ensuring the ultimate connection and power transfer.
