Audio systems with subwoofer connector

To subwoofer

— true to its name, this output lets you connect an external subwoofer to your audio system for powerful bass sound. Usually this feature is found in 2.0 format models — in fact, it allows you to turn them into 2.1 systems. And the external subwoofers themselves are convenient in two ways: the ability to place them at some distance from the audio system (to adjust to the characteristics of the room) and the abundance of their own adjustments (although not in all models).
