Default 12 inch SHARP Subwoofer sound cone help

Hello, I am in need of help for one of my speakers. I make music on the computer so i use these these speakers for my "studio" and one of the speaker's sound quality when hitting bass tones is worse than the other. But I feel like the problem is within the cone itself because when i push the cone back it seems to be clear without any disorientation in the sound. Is it the cone or is it something that's inside the speaker like the voice coil or the wiring or something like that. I have a video here to demonstrate my problem with a 808 sample

I'd appreciate any help on my problem, Thank you.

the speaker may have shifted within the magnet the misalignment would correct in the same way your describing putting pressure on the cone.

Are these a 2 or 3 way setup with individual speakers?

A stand alone woofer?

Or a speaker within a speaker?

It could be a bad cap or loose solder connection to an inductor in a crossover circuit, have you tried it with the speakers (or speaker) orientated facing down with a couple of books to act as floor spacers?

This could tell if the cone is hitting something or if the cone is tore, if you hear the same sound with the speakers facing down then the cone may have a tear or a torn flex joint.

Thank you Terryl, facing it down got rid of that noise that was coming out when it was standing up (my speakers are 3 way speakers) So it must be hitting something I just dont know what it could be hitting while standing up

OK, look for some small tears at the top of the biggest speaker, they can be very small, they may be in the top of the flex joint, if you find some then some rubber cement may be able to fix them.

A tear like that could cause the speaker cone to shift downwards and rub on certain sounds.
