I have two of those Dinky subs!
But that's okay cause I'm twice your age and then some.
The stands are sharp looking. If those are 150's on them I have a couple of those too. I have only ever seen two members knock anybodies gear around here. One is banned and the other is turning over a new leaf.
I'm curious if your center is a match for the mains. The whole set up looks good. Betcha can't wait for the house to clear out so you can crank it.
