New in the Gallo lineup is the sublime TR-3D Subwoofer. Its appearance follows the familiar lines of its direct predeccessor the TR-3 (and the TR-1D) but this subwoofer houses a completely new and improved set of internals.

At the heart of the TR-3D is a long-throw ceramic anodised aluminium cone driver, driven by a powerful 300 Watt Class-D digital amplifier. To make sure it performs to its potential in every room, bass equalisation options allow the user to adapt performance to room size. A small room probably won't require any boost, a large one might benefit from full boost.

TR-3D's cylindrical steel enclosure mirrors Gallo's spherical speaker technology, and allows for smooth, powerful bass - from 18Hz to 180Hz. Additionally, the TR-3 has a continuously variable low pass filter, from 50Hz to 180Hz, with a fixed 100Hz high-pass filter on high-level output.

TR-3D is finished in black.
