Is this bad? DId I get screwed?

[95Prober 10+ year member]

Hey guys,

I bought a used 12" d2 IDMAX from a member on here a while back and just got home to get a look at it. It came in the box undamged which was good, but I think he sent me a bad "semi-bad" sub.

Everything looks ok, no rips or tears on the surround, but when I push down on center of the cone, he seems like it rubs and a light scratching sound.

Is this repairable?

Any thoughts? Thanks

Use a DMM and check the Ohm load on coil or coils and see if they are were they are supposed to be.

But if it is rubbing on a direct push down in the middle of the cone then chances are something isnt right.

play it free air, you coud be pushing to one side of the cone causing it to rub. i do it alot when i first get subs but then free air with tones and they are good

You know you're not supposed to push the cone down right? The chances of you being able to push the cone perfectly in the middle are very small, and if you push off center, you cause coil rubbing, which is bad. dont push the cone.

you cant push the cone perfectly down most of the time, the fact that it scratches doesnt mean anything

When the coil scratches while pushing the cone: 1) adhesive is removed from the coil, and you have tiny bits of adhesive floating around in there=BAD.....2) you are also mechanically manipulating the coil windings, do it enough, and you will loosen the windings=BAD. DONT PUSH THE CONE

edit: at least thats my take on it, with my slightly higher than total noob's understanding of subwoofer engineering. Better to just not push the cone

test them out like mentioned free air and with dmm before making a thread. and x3 on pushing on cone. although im sometimes guilty of it but i push lightly just to see how tight the subs are for some reason lol. one of the first things people naturally do when they first get or look at a sub.

if you pushed hard I would imagine thats how it would be, but if you gently pushed on it, the results wouldnt be that drastic

True... I been found pushing cones, but very lightly, for the same reason as old school mentioned. However alot of people push them all the way, and from what I understand those id's dont have a super stiff suspension, so they are easy to push all the way down
