All Harmony Audio's Subwoofers feature interwoven tinsel leads that increase durability and performance.

The greatest enemy of a car audio subwoofer is heat which needs to be quickly dissipated for a sub perform correctly and is crucial to prolong the life of the subwoofer. The Harmony HA-ML122 Monolith series subs feature large slotted vents directly under the spider which allows cool air to quickly reach all the sensitive components.

Cutting corners is not the Harmony Audio way and while other manufacturers may be cutting out features to save a penny, we are focused on producing a superior performing subwoofer. Take the wire terminal for instance, probably one of the most important features of the sub, which is what handles the power transfer from your amp to the sub. Many other brands now use a cheap spade terminal that takes longer to install and who knows if it will even stay 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.
