Strange noise on BTL N2 at higher frequency bass

I contacted Fi. Waiting for someone to tell me what I should do or what might be happening. A friend of mine suggested that maybe there's a piece of magnet or something that flies around under the cap and re-sticks when the pressure is low again.

Magnets don't just fly off then re-stick, they don't break off easily either, if they do they just chip on the outside.

Doubt very seriously if it is anything of the above, the gap is way too big for the coil to scrub and it would do it at low frequencies, not at high frequencies...

You are positive you have your crossover set up properly?

i have a quick question nick not even about this topic (sorry) but why is it that the recones that we get from Fi are not the same as the original soft parts that come on your guys sub's? "cone" "surround" etc.. ??

We constantly change things up soft parts wise, the recones you have now are the latest rendition of changes and are totally sourced from here.

Oh alright was just kinda curious cause the originals seemed more heavy duty like cone stiffer and foam is thicker... and about the dual 2 coil comment being really dark i noticed mine are extremely dark when i got them today like a dark purple.. was kinda wondering if it was the glue or some type of thermal stuff cause my original dual 1 coils are like shinny copper lookin even posted a vid on my youtube channel

Dual 1's are lighter then dual 2's..and those cones/surrounds are in an extreme vehicle on the 180dB mark so i don't think you'll have a problem with them.

That dual 2 coil in that sub has been hot...it's nearly black. The D2s we have now in the last batch have been a darker brown color, but not black

Alright i have another quick question nick is the Glue you guys use around the former to glue the cone to former diff than the normal solid CA glue cause when i touched it it liek smashes in and if still soft rubbery feeling and tacky didnt know if this was normal cause most of the others ive done are completely solid as a rock

We used 3 different glues on our assembly...so yes, it is different.

There is nothing inside of there..as others have said, magnets just do not fly around and re stick or anything of that nature. Nothing moves in that motor assembly..

Send the sub in, we'll check it out.

Would love too. I have contacted sales but have not gotten an RMA yet.

[NDMstang65 403]

Fill out the warranty card, send it in..watch this video...otherwise..yeah Self explanatory.

[djanice1980 0]

The cap looks fine. The spider looks fine. The terminals look fine. I dunno what it could be.

Just a FYI, it really looks like you took that photo in black/white on your camera... Did you ??? Cuz it the basket doesn't even look the right color, let alone the coils...

yes i agree....does look like it's in black and white
