About the VTF-3 MK2

The VTF-3 MK2 is a 12-inch, front-firing, ported powered subwoofer from Hsu Research's Variable Tuning Frequency (VTF) series, using a hybrid tuning system with removable port plugs and EQ settings to optimize either maximum low-frequency extension or maximum output in different room setups. It employs an internal high-power amplifier driving a front-mounted 12-inch driver in a vented enclosure, providing deep bass extension into the sub-20 Hz range in its lowest tuning mode. The VTF-3 MK2 is a discontinued legacy model superseded by later VTF-3 MK3–MK5 revisions.
