i think you will be happy with a mid-sized, low tuned ported box.
its true that when you want a devoted SQ system, you would go sealed, because of the flat response, but when we are talking just a daily driver system, you can't go wrong with ported. my ported box has GREAT SQ and i could not be any happier with it.
the best part is, i can play any type of music and it still sound good, i can hit all the double bass kicks and hit the low lows in rap music. i was a little leary at first when i went ported, but let me tell you, i wont go back to sealed.
