The items you requested weren't the problem, the inconsistent category names are the problem. The "Main Speakers" category describes how the speakers are used, the "Bookshelf Speakers" category describes how they're designed. I brought this issue up with Chris, but it's probably far down the list of things to do. Until it gets resolved, I'll probably just keep listing all the floorstanding/bookshelf/main speaker additions under "Main Speakers".
