Hsu Research speakers and subwoofers are renowned for their pristine sound quality. And that hasn't changed in the last 30 years. With meticulous engineering, HSU products have continued to have an astonishing level of clarity, accuracy, and depth in their sound reproduction. The speakers boast a wide frequency response range, ensuring that every nuance and detail in the audio content is faithfully reproduced, while the subwoofers deliver deep, impactful bass that brings music, movies, and games to life. The precise tuning and integration of drivers, along with advanced crossover designs, result in a seamless blending of frequencies, creating a cohesive and natural soundstage. Hsu Research speakers and subwoofers excel in delivering an unparalleled audio performance that showcases the artistry and craftsmanship behind their products.

Exceptional Engineering

Variable Tuning Freqeuncy

Variable tuning frequency is a groundbreaking concept introduced by Dr. Hsu to the world of audio. Variable tuning allows you to choose how deep your subwoofer plays, on-demand. Choose between a music mode (lower bass extension) or a home theater mode (higher headroom and more impact) in just a few seconds. This gives customers an extreme amount of flexibility to set up and tune the response to their room and desires. Subwoofer designs involve tradeoffs – one cannot optimally design a subwoofer to play low deep notes, and at the same time, play loud with pristine clarity. Rather than making customers choose, HSU has designed its VTF (variable tuning frequency) series. We put the power into your hands: choose which trade-off works for your listening taste, room, and event.
