The "x" series are the newer versions of Logitech's midrange line. The x-530s replaced the z-640s. The x-230s replaced teh z-340s.
I can garauntee you that you're not going to find any speaker set for $100 that goes down to 20hz with any reasonable output. I spend $430 on my subwoofer and it's about the cheapest sub you can get that will go down to 20hz and lower.
The vs4121's may be vibrating if you give them a 20hz signal, but it will be very very quiet compared to the higher stuff. Subwoofers tend to "roll off" below a certain frequency. For example, my sub rolls off at about 20hz. My sub is still producing sound in the low teens, but it's so much quieter that you can't include it in the frequency range it covers. In HT speakers, the range is usually reported with a +/- 3dB rating after it... meaning that if it's 3dB quieter at a 20hz in my example, that's how low they say it can go.
In computer speakers like the vs4121's, they're probably reporting the 20hz based on the fact that it has some measureable output. They might be able to call it 20hz to 20khz +/- 30dB, but it's not really going to get very low.
I think the 35hz rating on the logitechs is a lot easier to believe. Below 20hz is where it stops being something you can hear and moves into the tactile range. 35hz is plenty low for music and will give you plenty of rumbling in movies if you desire.
The bass will be adjustable on the Logitech sets, so you can turn it down if it's too much.
