Sub bottoming out?

[audioholic 5,000+ posts]

A slapping noise could be multiple things, not just bottoming out the voice coil. It could be a loose spider, it could be tinsel slap, hell it could even be debris inside the box.

OP is running a sealed box, so I dont know why he's being told to up his SSF... he shouldn't even need it to be on, much less set higher.

i turn the volume down imediately when i hear it flapping, so i hope no damage was done

sounds like that weak *** amp is clipping hard and sending bascially straight dc voltage to the sub. his sub holds 500 rms and hes using a amp that is 520 peak. sounds to me like the amp is clipping way hard.

i set the infrasonic to 25 hz and adjusted the gain again, without bass boost or eq on the head unit. It seems like it hits just as hard if not harder, without bottoming out Thanks for the help!

i have about 40 volts going to the speaker, and the sub handles 1000 max. So i think i should be fine, but i cant be sure without an osciloscope. I was told the amp i have is good quality.

you need to throw out those "MAX" numbers as they dont mean jack. RMS is the only numbers that mean anything and on some cheaper amps they dont mean jack either.

i had the same problem with my btl's. my specs were all perfect for the box....but, when a deep low note would hit, it would draw more power than what the fuse is rated for. your prob. simply just drawing too much power for your fuse.

wat

wat

when the fuse was about to pop and or when it gets burnt a lil bit my subs used to act funny. when i put in a new fuse they would be fine.

Be careful with those rwes they dont have a lot of mechanical excusion and the coils are made with plastic formers so you WILL ruin the sub if you do this repeatedly

RWEs will bottom out if you dont have them in the right enclosure. the box should be exactly what it calls for or a little smaller, note if you go smaller it will not get as low.
