I have been so busy the last year that I could not complete the project although I have all the parts and built and lined the boxes for the five speakers. Here it is:2X 2Pi Towers
3X 1Pi (centre and surrounds)
I have not built the sub yet as I mainly watch music DVDs and my wife is not too keen about HT sound, but I'm looking at using the Eminence Delta LF (3pi??) with a subwoofer amp like the ones they sell at partsexpress. I am unfortunately in South Africa and can find a similar subwoofer amp nowhere. As soon as I build the box, I will pay more attention to the search.
I also don't have the HT amp yet but would most probably settle for a NAD or Denon.
Good Luck
