I am looking to purchase an L212 system and I have a few questions for those of you familiar with this system.

1) Are the original factory shipping cartons sturdy enough to protect the speakers from the likes of UPS and Fed Ex?

2) Is the amplifier used in the subwoofer a reliable design or is it troublesome?

3) Can the satellite speakers be used full range without the subwoofer?

I know these speakers have their limitations but I've always wanted to own a pair.
Thanks,
Mike
