you can find some used paradigm titans on ebay for that price or less shipped.
the key to that is buying them from someone who has packed speakers before and knows they need a lot of padding everywhere, and not just in between the speakers so they simply cant hit each other.
i just bought and returned a set of titans off ebay that werent packed very well. the woofers in boths speakers were separated from the cabinet/ the magnets were broken off the cone of the woofer in both because they didnt have any padding in between the box and speaker. the terminals left indents in the bottom of the box from being smashed down
