Oops, sorry yeah you've said several times it's three of the same speaker
Then I wouldn't be overly concerned about the height difference, you're gonna have your centre relatively high anyway, maybe make your stands for fronts an inch or two lower than you ordinarily might if they were your only speakers. Keep us updated with how you're getting on - photos of a build project are always good ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
