Just ordered a pair of 450's off E-Bay for 350.00. Thats all, no tax and free shipping. There brand new in a sealed box straight from an authorized DEF Tech Dealer who never opened them. I know there's no warranty, but feel the need to explore this avenue. If the speakers are good I'll get two more pairs, for a complete surround sound. I still have 7 days to return them if there broken, for a new pair.
In 2002 these same speakers cost 350.00 each and at authorized dealers, there still 650.00 a pair.
I'm taking a shot at this. Tell you all how it turns out
