I read through the thread a little and came across this. I have RBH T2's and the driver screws all started to show some surface corrosion. I noticed one or two had a slight orange hue to them but ignored it. After a few weeks, they all seemed to turn a slight orange color at once. I sent an email with a couple pictures to the guy I've spoken to a few times there and they promptly shipped me out a whole set of screws as replacements. If I counted right, there are 40 screws per speaker, so 80 total. Of 80 screws, only one of them was stripped when I tried to put it back in.
Not saying that will happen every time, but the screws came out and went back in just fine on mine. Figured I'd throw that in there.
Plus, the silver sure does look nice....
Black is just too subtle.
The beryllium midranges on the L/R are silver because they are the old versions. I bought the T1 center more recently and they have changed the beryllium to a slightly grey (almost blue-y) toned color to better differentiate it from the aluminum. I like the silver more, but who am I to decide something like that!
Mine have the grilles on them behind a screen regardless, but I did like the look and arrangement of drivers before I hid them
