"I'm aiming for the bass to shoot out far"....What you need is Power, the box is not important in this case. It doesnt matter if you get Sealed, Ported, or Bandpass, a box is only meant for the type of sound quality you want, not how loud it will sound. You can turn the volume all the way up and all 3 boxes will sound pretty much the same in loudness. Instead get yourself a powerfull amp, a powerfull subwoofer, and alot of watts. Then chose the type of box you want for sound quality.
