Mule,
OK, a bedroom system. Makes sense now.
I just bought a bunch of BIC Venturi tweeters from Parts Express. All on clearance. 10 in all. 4-1", and 6-3/4". Rebuilt a few bookshelves for the basement. I can't say if those tweeters came from the DV62si's, but they sound outstanding. A lot has to do with the crossovers. The soft dome tweeters actually handle quite a bit of power, and have yet to distort.
I gave away a set of Venturi DV62 bookshelves about 3 years ago to my younger brother. I had them in college, back in the early 90's. Excellent set of bookshelves for the money. I pushed the dickens out of them, and not once had to replace a driver.
My advice - for a secondary room, they're hard to beat. For a primary room, they'd work great for surrounds.
