The Blaupunkt is not really the best choice for a vented box of 2 cubic feet.

Here is a great 10" long stroke woofer from Peerless that is within your price range and almost made to order for such an enclosure. Ten or twelve years ago, this speaker's predecessor was about as good as it got in the subwoofer department at almost any price. Subwoofers have moved up performance wise, but this speaker is still a great value for the money. The only difference between this speaker and it's predecessor is the fact that the new composite cone extends the smooth response up to the 1500 Hz.

Following is the WinISD graph showing it's excellent response in a 2 cu ft box vented to 27 Hz.

now you guys say why all the others are good but you are not telling me why blaupunkt is bad!
i relly dont understand why is is so bad i have washed the specs through quite a few programs and they say it is very good....
and so do reviews....
also my friend has one and i think is sounds good......
why are you guys trying to get me to get a different woofer for a first project? i am not looking for perfection...

and if the blaupunkt is so bad why?

thanks,

keep post'n

If you've heard your friends and like it then go for it you have nothing to lose. But don't get discouraged when you post here and people recommend different products than you had in mind. Everybody has a "pet" sub or amp that they like and it's the nature of the audio freak to recommend their favorites to everybody who asks.

With regards to the graphs, they're showing the drivers frequency response. You want to avoid a driver/box combo that has lots of peaks and dips in it. A smooth fairly flat line that drops off slowly at a low frequency is what you're generally after. This is quite simplified, but at least now you should know basically what they are.

The plot you posted has a small hump centered around about 60Hz where you're up a little more than a decibel. Looks to be -3dB somewhere between 30 and 40Hz. Which isn't bad at all.
