About the VTF-1 MK3

The VTF-1 MK3 is the latest iteration of Hsu Research's VTF-1 series, designed for high performance in small to medium rooms up to 3000 cubic feet. It features a front-firing 10-inch reinforced paper driver with dual front-firing ports and a powerful 250-watt RMS (1000-watt peak) BASH amplifier that combines Class D efficiency with Class AB fidelity. The subwoofer offers variable tuning with five operating modes including ported and sealed hybrid configurations, allowing users to adjust bass extension and output to their preference. It has a frequency response extending down to approximately 20 Hz, with a crossover frequency range of 30 Hz to 90 Hz and a 24 dB/octave slope. The enclosure is compact and finished in satin black paint, measuring 18.5"H x 14.5"W x 17"D (19.5"H with feet and grille) and weighing 42 lbs. Connectivity includes left/right unbalanced inputs and speaker-level inputs, with a 0°/180° phase switch and adjustable Q control. The VTF-1 MK3 is praised for its accurate bass, good extension for its size, and value, backed by a 7-year woofer warranty and 2-year amplifier warranty. It is suitable for both home theater and stereo systems, offering flexible placement options and integration ease.
