About the VTF-15H MK2
The Hsu Research VTF-15H MK2 is a large, high-output powered home-theater/music subwoofer. Its Variable Tuning Frequency (VTF) cabinet uses a front-firing 15-inch fiberglass-reinforced cone woofer, dual triangular front ports, supplied foam port plugs, and rear-panel EQ/Q controls. It can operate with two ports open for maximum output, one port open for deeper low-frequency extension, or with both ports plugged as a sealed subwoofer. A custom BASH amplifier is rated at 600 W continuous and 2,000 W short-term dynamic. Inputs include stereo RCA line level, balanced XLR, and speaker-level connections. Hsu lists the VTF-15H MK2 in its current subwoofer lineup as its highest-output model, while continuing to provide the manual and specifications.
