Confused over the Logitech Z-5450 Speakers?

[AFK_Matrix]

I have been looking around at the prices of these things and I seem to see 2 set of prices. One is about 100 quid cheaper than the other. Now what I am wondering is do they do 2 types of these speakers?

Ie one with wireless rear speakers and one with wired rear speakers?

I was also wondering between the Z-5450s and the Z-5500 which are the better set of speakers? I belive the subwoofer on the Z-5450s is smaller is that going to mean a lot of difference?

Thanks

Thanks for the reply.

I know the Z5450 subwoofer is smaller than the Z5500 but is this going to affect the sound quality i get as tbh I won't be able to really crank the bass up for a while as I will disturbe the neighbours

Also whats bugging me about the Z5450 is that i have seen 2 different prices for it. I have found ones for £150 but they mention nothing about the wireless back speakers. And then there are ones for £250+ which do seem to mention the wireless speakers so I am therefore wondering if there are 2 different types of Z5450s?

NM i think i see whats happened the shops are calling the Z-5400s Z-5450s and they look exactly the same except the z5400s don't have wireless. Bloody shops
