Well as nice as it was, I decided to return it. It developed a bad speaker rattle and I didn't even push it. Oh well..... too good to be true I guess.

I'm assuming you tried tightening every screw on the outside of the combo, popping the cloth grill and frame off and seeing if the screws holding the driver in place were snug, making sure when you replaced the grill that the velcro was holding the grill securely.

It's possible the 10" driver is faulty, but I'd make a bet, there's nothing wrong with it, odds are, the rattle is from the grill not being fully snapped into place.

Things coming loose during shipping can happen to any manufacturers equipment no matter the price.

I had a high-end, high-dollar bass cabinet develop a rattle right after I received it.
Turned out to be a wire inside the cabinet rattling/buzzing against one of the drivers.

Yeah I did tighten everything and the rattle persisted. I even looked inside the cab with no luck.
