Sure, but honestly - when it comes to subs (I learned this the hard way a long while back), it is SO much better to 'wait and save, wait and save'. That Velo-10 is a decent subwoofer, but I doubt you'll see much of a difference over your current Klipsch for what it's worth. If you want REALLY awesome low-end in your system, employ a little patience and spend the bucks to get you to that level. I ran through a series of lower end subs back in the day and ended up spending much more money than I would have, had I just waited and saved for the right sub. Trust me, you may have to sacrifice not having one for a while, but it will be so incredibly worth it when you finally pull the trigger and get one.
