Thinking of getting a pair of Wharfedale Diamond 9.1 but won't be able to see them before purchasing. If anyone has a pair would they be kind enough to measure the depth of one for me. They are quoted as 278 mm deep. Does that include the grill? What about the connection posts on the back? Looking at a picture I found on the Superfi web site it looks as though they protrude out the back. I need to know how much depth these speakers need with cables connected. With or without banana plugs (assuming wire can be connected directly to the posts) as I have limited space. Thank you.
