Ultra Instinct Subwoofer
I already had a crazy good 400w sub. Not just a good sub, but a crazy good sub. Somehow, THIS ONE IS BETTER. Way better. Very powerful, yet it handles that power with class. MUCH more powerful than my 400w sub. This Hsu sub has a wonderfully unique lush depth of sound I've never heard from a sub before. Thought the refinement mentioned might mean it was weak. No way. This thing will beat the block down. Luscious deep bass. I've wanted to try a Hsu subwoofer for years. I am deliriously glad I did. Customer service is beyond excellent. What are you still reading this review for? If'n you're curious, just get one, and you will see. I should have done this two subs ago. "Impressive. Most impressive."

I enjoy this sub a lot. What led me to this brand was word of mouth and reviews by others. And when I reached out to staff to confirm sizing of the sub paired with the room staff was responsive and helpful. And Dr Hsu offered me a minimal discount. It’s very powerful even if it’s just a 12 inch sub. And I recommend it to others. With a basic Onkyo receiver paired and calibrated with Dirac live the sub performs flawlessly. For me I use a q of 0.3 and volume about 10 o’clock with the panel set as “out” for crossover frequency.

Amazing sound
What I have experienced so far has been amazing! I have yet to dial the unit in to my system. I’m sure that it will be fantastic!
