Hi. I am just trying to find out what subwoofer would have the best of both worlds, sq and spl. I need a speaker that will hit like a monster when I push it, and it will sound good when I just want to listen to music. I do not want a speaker that will always override the highs and mids when I am just trying to listen to a rock song at low to medium volume levels. Thanks to all who give me any suggestions.
