Hi,
I would like to make a suggestion on the speaker grille holder for the QS8. I notice the grilled holder on the QS8 that is covering the woofers are made of hard plastic and looks very fragile. If they were the same as the EP350 or M60 grille holder, I wouldn't have any problems.
Unfortunately, they're not the same as the EP350 or M60 grille holder and they break easily, at least in my case. They probably broke during shipment when the speakers are moving/sliding around a little bit on the styrofoam.

Suggestion:
Change the grille holder on the QS8 to the same type found on the EP350 or M60.

Thanks!
