Yes, it was completely done without anyones help. Except the occasional cleanup help from my wife. I have adjustable brackets for the center channel speakers, but have found the top one will need to be about 16" away from the wall to get the proper projection, due to the angle and the 9' ceilings.

The center channels crossovers have accuately match components (about 5 lbs worth) and the drivers were selected out of the bunch to ensure they matched as closely as possible to each other. They don't show it in the pictures, but each weights about 40 lbs and have very clear transparent sound, never harsh. They are the only part of my last HT that I could not let go of and I cannot say how much I enjoy there sound.

I have not tweaked the projector yet, as I wanted to get everything in the loop (990) before I did so, as I find there is always impact by anything added. No matter how good it is..
