So, I did a quick translation from German and want just to confirm: Mona Kea is 100% open project with a full information for building here: https://www.donhighend.de/?page_id=4005 , nothing missed or hidden. Second, where can I buy all Monacor speaker drivers with shipping to Canada? Also I realize that driver SP-6/108PRO might be an issue ( discontinued ). I will hunt for SP-6/108PRO first , if I get it , can buy the rest after. Thanks.
Soundimports.eu will ship overseas I think. Amongst others. Did you try the Monacor webshop?
You are right about the 6". Try to contact Alexander and inquire if he has found a replacement. I don't think so, his comments from last November point out he's not changed anything. The SP-6/100Pro seems to be a 4Ω version of the same mid woofer, but that isn't going to help much. The crossover could be adjusted, but that isn't an easy task. Just my 2 ct: if you can't find the drivers, don't build this design.
