Well i hooked them up. All i can say is WOW. It hits really good lows. The song Soul Survivor really hits good. To me, its just as loud if not louder than with port in the middle tuned to 40Hz. Im guessing the rattling was my box because it has stopped now but my speakers do smell kinda bad. It will blow a girls hair around if she puts her head inside my window and this is not with the wall completely walled off. Ill prolly put the panels back on tomorrow and ill post pics.
