It has plenty of output, don't judge a sub by it's power ratings, there is a lot more to it than that. I was having amp problems with the dayton, but partsexpress has been good and replaced the amp twice under warranty with no issues, so I can vouch for their CS. But I'm not using the dayton in the same room as the PB10 anymore, but I did originally have the dayton in my bedroom. The sound quality isn't as good as the SVS, and it doesn't hit as low or deep, but it still has plenty of output. As long as your room isn't too big, I think for the price it's hard to beat the Dayton subs. They are a good starter sub, but you would be best off to just take your time and save up for something really nice. I would have kept the PB10 and sold the Dayton if the PB10 had speaker level inputs, but it's the only sub they offer with that basic of an amp, so instead of getting a new receiver for a system I seldom use, I figured I would just sell the SVS since the amp in the dayton has been doing good so far. My girlfirends mom has the dayton Sub-100 10" sub and it too has plenty of output for what it is, but both rooms I have listened to it in are fairly small, but I would still get the 12 since it's not that much more. But again, I would save up for something really nice like the PB12-NSD or even a SB12, or even one of the offerings from HSU Research.
