why do you laugh? he is right, 10"s are pretty much the best mix of both worlds.
and its a fact, smaller woofers do not get down low, and bigger woofers sound worse than smaller woofers... the only downside is that if you want to get loud and sound good then you have to have alot of smaller woofers //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif . unless you are fine just sounding medi-ocre, then you can use 12"s.
there is alot of mis-information in this thread. there is a direct corelation between cone size and output/SQ //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif . i would make a graph to school all you people, but i dont have excels.
