Subwoofers
What causes the "fluttering" noise in subwoofers and how do I prevent it?

[QUOTE="RaceDVS, post: 8810884, member: 680447"] I've been retuning my system from the shop by ear, and noticed a painful fluttering sound the day after playing around with too many beers in mah belly. 2 Alpine Type R2s in a generic sealed box - once I opened the Arc Audio X2 amp and lowered the gain a hair, set the subsonic filter (people say sealed boxes don't need a subsonic filter set but that's BS) after boosting the sub signal on my sony xav ax5500 head unit by just a couple notches it was gone and they began to hit HARD and clean.
