Hello all... I look forward to learning more about this expensive hobby of ours! I currently have a klipsch sub-10 and it has served me just fine with no major complaints thus far. I have the opportunity to buy a used def tech supercube 2 for $300. This seems like a pretty good deal.. My question is: should I expect some kind of night and day difference between the klipsch and supercube? If I get it, I was thinking I could hopfully sell the klipsch for around $200ish and I would only have $100 into the supercube... Or should I keep both?

The guy is moving tomorrow, so I have to act quick. I greatly appreciate any input anyone can contribute toward the subject!
