Can you SEAL, then PORT a passive radiator subwoofer? Yes you can. Let's open this thing up.

This Dual 10 inch 2400 watt subwoofer is back with a vengeance to prove itself after blowing up a passive radiator in the last video. In this video I morph this thing from Passive radiator, to sealed, and then to ported. I also test and listen to each different rendition. The results will surprise you. #dualsubwoofer #subwoofer #homeaudio #bass #diysubwoofer
