Up for sale is a HSU STF-2 Subwoofer in black. The sub was purchased in March 2007, and still has about five years of the 7-year warranty (which Hsu Research has said is transferable, as long as the serial number is visible).
Cosmetically, scores a 6/10 (to be safe) on the Audiogon scale because of a few light scratches on the top that are only visible under bright lights, and a small ding on one of the corners (see picture). The subwoofer plays fine, however, and comes with the spikes, brass plates, and power cord.
Unfortunately, I no longer have the manual (available on the
product page) or the original box, so I would prefer a local sale. If I do ship it, though, I would send it well packed and insured. I'm located in the CA Bay Area (95070) and Sacramento (95616).
Let's say...
