You should read this comparison of a few computer speaker systems.

It is pretty interesting because the reviewer took some of the stuff to take internal photographs. They have a Creative system in there. It appears to have an 8" driver, but when the guy unscrewed it, it turned out to be a passive radiator... with a <6" driver behind it.

I have a Adire Shiva which has an 87.2 dB sensitivity, and when playing music 40w is enough to get you evicted.
But, because of the increased dynamic range (which results in lower average output) DVDs are a little quieter than I would like.

I would recommend choosing a driver (with as high a sensitivity as possible) and then figuring out how much power you need.

How much are you looking to spend? Do you have any amps already?

i think 50watts is plenty. i built a bandpass subwoofer from a radio shack 8" driver and it was loud. then i Built another one useing a kicker c10 9 compitition sub ) and used it in a bandpass box too. It killed my 15" usd subwoofer. if i had the chance again i would totaly use the kicker c10 in a bandpass configureation. also i only ran about 90watts into it and it was VRRY VERRY loud and 15w was efficient too. I loved it. i would sujest building one..
