Logitech speakers

[nricexbox]

I'm trying to decide which Logitech speakers I want to buy. My cousins were lucky enough to decide on the 5450's and get a steal with the xmas discounts, but I can't seem to find and decent deals anywhere. So I'm wondering, I see the only difference between the 5450's and others is the dual subwoofer. Is that one difference worth it?
Thanks.

The 5450 is a waste of money if you ask me. Just because the rear speakers are wireless doesn't mean you have to pay a freakin' high premium for it. That too, its got a just 310watts RMS or so.

I am a bit confused though, which high end logitech's got a dual subwoofer? The 5500 doesn't have one, neither does the 5300/2300...
