check your RCA Cables, i had a buddy who was running very nice am and subs and they were playin all distorted like, and after many trips the the car audio shop and lots of trouble shooting we figures out it was his RCA cable had been cut into half way by a peice of metal, we saved his 1,200 dollar system by replacing the RCA's

just recheck the connection and all the way down,

Rs have a very large dustcap, which i guess would be double coned.

The glue on the surround sucks, i was able to pull it off with my HANDS and the surround was still perfect.

i tore apart several good team rf's.. who cares?

it was in a small sealed enclosure. Don't have the exact measurements at the moment but i know it was not ideal for a type r. I will get pictures of the motor structure tommorow.
It was ran on high frequency. i had the crossover at 250 hz with the LPF on (For about 2 days before noticing). I had the amp screwed in facing the other way becuase my battery is on the right side of the car and I thought i had it at 50 hz but i thought wrong. (I'm young and i still have alot of mistakes to make and learn from, taking apart this woofer may be one.)

What damage would high frequency do to the woofer if any?

High frequencies will not damage the sub.

Can you get any shots of the tinsel leads? They may have been getting worn and not have a good connection. There could also be something in the gap that caused issues but the coil doesn't look scuffed at all.

its not the rca becuase i currently have an sx which sounds fine.

I will try to get to the tinsel leads. They are in that little box which is a ***** to get into.

call me a noobie, but what is the former?

It is the tube that the coil is wrapped around.

So i decide to take apart my "blown" type r because it sounds like dookie.
I took the cone, spider, and voice coil off and have it still together as one piece. I took a look at the voice coil and there seems to be nothing wrong. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

I was expecting it to be warped or fried but i don't think it is.

When i played it before tearing it apart it sounded as if i had the gain turned way to high on the amp but it was down all the way. I was only running 300 watts to it and it was just makin a farting type of noise, as if there was a bad connection.

There is nothing wrong with the amp because it powers the sub i have in my car just fine.

Any suggestions towards what could be wrong?

Oh yea i will be posting pics later to show whats up.

Isn't that the signature sound of the Type R? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Joking of course.. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

hahaha yea. it was extra loud though as if it ate some taco bell for lunch.//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

so i got to the tinsel leads and they look fine. Ill get some pictures up after i charge the battery to my camera.

Im thinking its the former is a little bent. Anyway to fix this?

and what could have caused it?

 

[BumpMW 10+ year member]

ok so i prolly didnt mention i had 2 of these with the excact same problem. I did some further testing with the other one in free air and it seems that it is only making the front of the woofer. if i put my head next to the side it sounds just fine. Do you think it could be that the cones are rubbing together?

 

[KingSham 10+ year member]

maybe it was becuase it was in a small sealed box?

 

[BumpMW 10+ year member]

so being in the small sealed box is what bent the former?

 

[Atimm693 10+ year member]

By bent do you mean just a small edge, or is the whole thing off shape?

I had to dissect one that supposedly had the cone "starting to separate" but the thing was all the way off.

 

[BumpMW 10+ year member]

i cant see anything bent on the former. i can push down one the middle of the woofer without making any scratching noises but anywhere else it scratches.

from the looks of everything the cone and dustcap seem to be fine. this is really starting to tick me off.
