VTF-3 HO w/ Turbo

About the VTF-3 HO w/ Turbo

The Hsu Research VTF-3 HO w/ Turbo is a modular, variable-tuning powered subwoofer based on the VTF-3 HO platform and equipped with the optional Turbo Charger top module that extends and re-tunes its dual ports for deeper low-frequency extension. It uses a front-firing 12-inch long-throw driver designed for high output with low distortion. The built-in BASH amplifier is rated at 500 W RMS and up to 2,000 W peak, providing substantial headroom for demanding movie and music content. The base VTF-3 family provides tunable low-frequency extension around 18–22 Hz via port/extension settings, and with the Turbo module attached the system is tuned to approximately 18 Hz with twin 4-inch ports, trading some maximum SPL for deeper extension. The amp includes a 30–90 Hz low-pass crossover with a 24 dB/octave slope that can be bypassed, along with variable level and phase controls for integration with AV receivers. The VTF-3 HO w/ Turbo is positioned as a high-output, value-oriented subwoofer delivering very strong deep-bass performance in medium to large rooms at a direct-sale price point well under typical flagship models of its era.
