4HT:

You might consider changing your fronts to small and experimenting with crossover settings. I think you'll probably get better performance out of both your sub and your fronts/center.

I think the red dot is just for those of us who got refitted 950's after trading in our original units. It identifies the factory refitted units. If you have just received your first 950, you may not have a dot. (Someone else can correct me if I'm off-base here.)
