You can probably flip them for $120-$150 after they get sold out.
There are some guys selling the Infinity R162 for $310 on Amazon.
I expect they are buying them (I think Harman Audio limits to 5 pairs) when on sale for $200 and selling them at $310. When they are no longer on sale, $310 is still a bargain, it sure beats $450 (MSRP) and if a buyer waits for the next sale, there is always a chance that there won't be a next sale (although they have been playing this game for years).
But yeah, you're right, you don't need another (very nice sounding) speaker (at a screaming deal price of $80/pr)!
