Most folk here at AK don't jive with the Sansui speakers. They're typically labelled "Kabuki". So you probably will get a lot of less-than-positive replies.
Nonetheless, this doesn't mean they are bad- they may sound good. It'll be best to audition them yourself however, to see if they are a good speaker to your ears.
Can you try 'em out with an amp there at goodwill? See how you'd like them?
I've taken to carrying a small radio shack speaker with me to check out amps, and an iPod with a specific playlist as a source, and have thought of getting a small, portable battery operated t-amp. The battery-operated versions are much cheaper than the super-t, and would be a great way to test gear.
I'd give 'em a listen, as they may be good, possibly very good, but consensus usually says nay.
