Well I finally pulled the trigger and put my money where my mouth was recommending DIY Sound Group speakers. 3x HTM12 kits and 4x Volt 10LX kits have been ordered. Parents are in the US until end of March and will be bringing them back for me. Could be quite a while before they get built though. Will depend how quickly the theater rebuild happens. The larger is an HTM12 and the smaller is a HTM10. 12" vs 10" driver and 15" vs 12" waveguide.
