Good advice.
Just wanted to add, what you will be happy with also depends a lot on what type of music you listen too. IMO, an average 10" does not go well with rap/pop, it's OK for rock and it would be ideal for country/classical (or maybe it's just ideal for old farts????? //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif ).
Also if you are going to try to make it work for rap, I'd probably bite the bullet and attempt a ported box. Just my opinion, but a sealed 10" doesn't "boom" a whole lot.
