I would like to get a lot of replies to this. I was kind of under the inpression, that passive was the way to go, with subwoofer's. But now that I have done a little research, I see that active is the only way to go. I thought and thought, that I didn't want to have to plug in another cord to all ready bungled up mess of cords and wires, behind my stereo cabinet. So I took the plunge, and ordered a new subwoofer. I hope that I am right, and not just snowing on my furnace.
