Rattles on deep bass.
Took of the grill. That's not it. If I sit on the subwoofer, it helps a little. The ratling appears to be at the speaker/driver itself. It's only if I turn it up too loud.
Is it toast? Anything I can do to fix it?
What would I look for?deep bass generally means excursion based.
I'd pop the driver (be sure to unplug everything from the sub----AC included of course) and see if anything is obviously amiss. You might get lucky and it could be something as simple as a wire tapping against the back of the cone. 9/10 this turns out to be a derped driver though. If the unit seems fine otherwise check around to see if you can find a cheap replacement driver.
In a cheap replacement driver? Ideally you could find the t/s parameters of the current unit(maybe mirage will send them). If not, make sure....What would I look for?
