This is my SI d2 15" subwoofer that is dual 2 ohm voice coil. About 2 weeks after I put my sub from ported to sealed, this started. It sounds like I have an air leak and when I checked I dont. It only makes the sound when turned up real loud, but when turned up a bit the bass sounds fine. The following ohm readings is what I found out. What do you guys think




(dual voice coil, one reading for each coil)
