  • Aluminum Alloy Lightweight Cone

  • Butyl Rubber Surround

  • Tinsel Leads Woven into Spider

  • 2" Copper Voice Coil

The aluminum alloy lightweight cone is way more rigid than plastic or paper. It’s able to give an extremely quick flat linear bass response achieving the most accurate sound reproduction possible while having less distortion. It also has a better heat absorption allowing you subwoofer to handle some serious power.

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 Cheap outdated spade terminals take more time and effort to install and to keep it connected once installed.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