Whatta Ya Think About Hsu Research Subwoofers?


I’m in the market to add one or possibly two subwoofers to my stereo set-up.  I would like to spend $1,000 or less per unit, and that puts some of the higher-rated units out of reach.  I came across an ad for Hsu, which I had not heard of before.  I didn’t want a Chinese product and it turns out that Hsu Research is based in California and founded by Dr. Hsu, who has a Ph.D from MIT.  Audio reviewer Steve Gutenberg gave one Hsu product a positive review.  I was wondering if any of you have experience with Hsu and could share your impressions/recommendations with me.

My existing set—up is:  Parasound P5 pre-amp with Parasound A21 amp;  Martin Logan 60XT tower loudspeakers.  Thanks!

Erik beat me to it. They make a great product and are not priced in the stratosphere. I had an original VTF-2 and it was great. Their Variable Tuning Frequency design gives you more flexibility to tune the sub to your room. 
They have as good a return policy as anyone, and Mr. Hsu has been at this a very long time. I would not hesitate to recommend someone give them a try. 

Oops, sorry, not listening to them right now, forgot they are only on the HT loop right now. 

Still, I stand by my comments. :) Hsu are seriously underrated.
