Summer Project - Replication of MBL loudspeaker 10

As the tittle suggest I am on a journey to try and replicate my dream speakers. Here is a link to my thread which is located over at Diyaudio.com. I need a little help determining the measurements as seen in the illustration provided. If you or anyone you know can and will help I would love to hear from you. Pm or post here.
