Got my sub back 3 days ago and put it in. Worked fine until today, low volume it started sounding like this. This is exactly what my RE sounded like when I got it back and we came to the conclusion it was because the magnet was cracked. Well, this magnet on the new one is perfect.

What the **** is making my subs do this? It's wired correctly to 1 ohm. It's in a nice ported box. Gain is set LOWER than what it should be at. Theres no reason this should be happening

just sounds like ur pole vent pluged with air tring to blow around it.

i spent a hour cleaning all the metal chips out of this motor and then blew 125psi of air in the gap, it was clean. only issue i had after that was the limited excursion the motor is capable of because of the dual 3/4" slugs,non counterbored back plate with a non extended pole.

open vents in basket could have ****** something into the gap.

i freeaired the sub for over 10mins with 600rms on my test bench and wasnt a issue.

Just found another motor so I'm gunna be sending you some more business man!

the prob with this motor limited the rearward to 23.5mm if it was bottomed out can be real issue. i warned him of this issue before i built it.

i stand behind all of my builds but i cant counterbore the bottom plate for more rearward throw.

eather something got ****** into the gap or sub bottomed out damaging it...

I just find it wierd that both subs that you built me (the re SE and this one) make this noise. I don't think it could be the motor hitting the back on this one because the re did the same thing when it was grinding on the motor. They both still beat hard but when turned down I hear that same scratchy ugly noise

It also makes a scratchy noise when I push in on the cone

I tried blowing air in both of them, no change.

Any other ideas?

i sent you a freeair vid and there was no scratchy noise. check u didnt burn up this coil up too? look with a flash light.

u could have ****** something into the gap with wide open basket vents if the box wasnt clean.

i set up a new test bench a couple weeks ago so i could really test subs really well and run sweeps to throw some excursion and was no issues.

if you dont push perfect center you can rock the coil and make it rub,can do this with any sub.

just hope the chrome isnt flakeing off the pole. i cleaned alot of chrome flakes out of the gap...
