The Definition of Power

The Monolith Series is our top line of subwoofers thanks to outstanding power handling capabilities. They are equipped with:

  • Competition Grade Paper Cone
  • 3" CCAW Voice Coil
  • Stitched High Roll Foam Surround
  • Tinsel Leads Woven into Spider
  • Die-Cast Aluminum Basket
  • High Flux Ferrite Magnet

All these features contribute to one of the highest RMS power rating a subwoofer can handle.

Leading The Way

A tinsel lead is the small wire that connects the voice coil to the input terminal and if you look at most other subs its positioned so when the subwoofer is playing the cone will actually slap into the leads creating a pop noise when playing. The advantage to an interwoven tinsel leads is both increased durability and performance.

Advanced Air Flow Cooling System

Harmony Audio Flatline Series subs feature a unique fin shaped heatsink that transfers heat away from the voice coil.

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 Cheap outdated spade terminals take more time and effort to install and to keep it connected once installed.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.
