i was planning on geting a 15" magnum d2 but i have seen this sub discribed many times as being "punchy". this sounds like this sub is meant more for like rock music and fast quick bass lines not deep rap bass. correct me if i am wrong i am just a litle bit confused. wouldnt the 15 be a little deeper? would this sub be fine for rap or does anyone have recomendations for a sub a little better suited for rap than rock thanks
