GK Neo 210 cab "rattle"

[bound'n'blocked]

I have an older GK neo 210 cabinet, maybe an earlier generation cabinet. I've only ever powered it with an MB200 or an MB500 head. I play an active (or occasionally a passive) five string bass. Lower strings or notes like the E or B cause a rattling, farting noise.

Blown speaker? Something come loose in there? I don't think I've run too much through it. At eight ohms neither head would have been too many watts...at least I wouldn't think anyway. I seem to remember that it started after around a year or so. I've had the cabinet for maybe five years, bought new, to give you an idea of it's era.

Any ideas? Anybody have one of this time frame and had the same issue?

EDIT: mine is a standard upright cab, not one of the tilt back cabs.

Snug up the screws maybe?

Is it the grill rattling? The Neos can do that. Mine does.

BadExample and petrus61 --

I was thinking (hoping) that might be the issue. I'll give it a try...thanks!

Well...it's worst case scenario...
Shifted pole in one of the speakers... guess I pushed it a little harder than I thought..

Time to find a speaker I 'spose...

You can put Your hands on the cone and push it inwards slowly. You can usually hear or feel if the voice coil is rubbing. There is a high chance that the speaker went Beyond it's xmax and stroke the pole piece on it's way back.
