Hello and Happy New Year,
I’m very pleased with HSU (pronounced “shoe”)subwoofers, of which I have two. My older HSU sub is their VTF-MKII. I recently added Dr. Hsu’s (MIT PHd -engineering) newest and most powerful model, the VTF-TN1. Both are accurate or I like to say “tight and right”. Dr.Hsu has been designing subwoofers for over 40 years at his small facility in Anaheim.Ca
Rather than go into descriptive detail in this post I suggest that you visit.
ps I think you will also be very pleased with the prices. Also if you call Dr Hsu he frequently answers the phone himself. He’s a brilliant engineer, easy to took with and is a subwoofer “whisperer”. :)
Enjoy the music
