The Gallo Acoustics TR-3D subwoofer is a high-output, dynamic subwoofer designed for both music and movies. It features an array of capabilities and precise bass control, with the rear panel providing continuously variable phase and low-pass frequency, as well as bass EQ from 0 to +3dB and +6dB, transforming any room into a concert venue or cinema. At the heart of the TR-3D is a 10″ long-throw ceramic anodised aluminium cone driver, driven by a powerful 300 Watt Class-D digital amplifier and featuring our patented S2 bass loading technology. To ensure 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-3D has a continuously variable low pass filter – from 50Hz to 180Hz, with a fixed 100Hz high-pass filter on high-level output. The TR-3D subwoofer is finished in satin black.
