I'm just about to buy a Sony SAWM40, which is supposed to be a good BUDGET sub. I know you guys are laughing since yours are all like $800+. But still, about $200 is my budget for now. Is it possible to use that same money to build a sub that performs better than the Sony? If it is possible, could you direct me to some really basic sources of information? All the DIY sites (and posts) I've looked at aren't helping me understand things at all, but I may not have seen the right things yet. Thanks for any help you can provide!
