Hi Doc, I have found a reasonably priced new Marshall 2x12" Celestion speaker cabinet rated to 160w that might be an easier option that trying to build a cabinet. Here is the link and a shot below..... http://www.ebay.com.au/itm/Marshall-...kAAOSwxH1UD9G6
Cheers mate, I might seriously look into buying one of those once I can get together the money to buy one, I've got that bookmarked now.
