What is a passive radiator? With the TB tube, it is positioned opposite the primary subwoofer within the enclosure. Unlike a conventional subwoofer, it lacks active components such as a magnet or voice coil. Working with the subwoofer, it elevates bass performance without needing a significantly larger enclosure.
