If I were you I'd get a 15' Type R and port the suckah. The sub would only cost around 200$ which would leave you 100$ to have someone build you a box. The reason I would pick the Type R over what other ppl are suggesting is, b/c you can go pick one up at bestbuy or w/e and not have to rely on others experiences and actually go listen to it yourself. I only buy from experience and as much as I hear about RE, Adire, IA.. I have yet to hear one //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
oh and btw, if you do go with the type-r.. you prob wouldn't have to pay shipping depending on where you buy it from. so that helps a bit //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
