So i have a couple cerwin vega's and an external;l 15" sub woofer. Its an audiosource sw-15 and i did some mods to it to make it sound better. Anyways, even after the mods it doesnt sound even near as good as my JBL 10 that i have in terms of crispness and tight bass. So i was thinking about stepping down from the 15" and going for a 12". I want something that sounds great with music seeing as thats all i'm using it for. Any recommendations?? Thanks guys
