Great subs. They were over packed and protected to the point they could probably fall down the stairs and not be damaged (do not attempt.) I love the finish and more importantly the sound. After calibration they fit into my system seamlessly and provide a clear deep bass that can be felt even in a fairly large room. I highly recommend.

I can without hesitation recommend the HSU VTF-TN1. Tons of good clean bass. I will be ordering a second TN-1 in the near future. My home theater finally rocks like it should. Had a pair of 12” Klipsch subwoofers. The single TN-1 blows them in the weeds in both loudness and depth. Absolutely no contest. My thanks to Dr. HSU! The finish of the cabinet is first rate. It sounds as good as it looks. I also love the form factor. James Larson of Audioholics says this is a great sub. Now you can’t argue with the experts at Audioholics. 👍🏻👍🏻

This subwoofer is absolutely insane, it fills up my entire open plan living room with incredible bass even at just 60% volume. I had a full 5.0 setup for years without a subwoofer and didn’t know what I was missing. I think the form factor of the TN1 is also great, with it being tall rather than deep I can position it rather easily.
