Opinions on a cheap sub?

[Icecoldblue]

Was curious to what you guys think of this?

I'm not really sure if it has any x-over controls or anything, would have to go look at it. Even if it doesn't have a x-over control, i should be able to control that via AVR anyway, right? The spec sheet is saying 100 Watts total (judging by the rest of the site), I'd guess the RMS would be around 50 or so. I'm a little concerned that it weighs 11lbs lighter than the psw10 (15 vs 26).

This thing would be paired with some RB-61's to use as my "Computer Speakers", and hopefully cure my need for a sub (for now ).

But for 60$ I don't really see a downside... Other than it could catch fire and burn my house down
