Hi Troels,
I finished OBL-15 yesterday. First of all I'm really grateful for your sharing and kind returns. Kit coming from Jantzen Audio arrived in perfect condition with very good packaging. It took about a month to build up. From the first second these speakers sound fantastic. Yes I'm sure they need to be break in but even now they sound so much satisfied well balanced, musical, rich, almost no distortion on high volumes, having huge soundstage (especially on classics) and extra ordinary dynamics  JA8008 HMQ and Audax drivers seem to be pretty good and you sure woofer (Ciare NDH 15) selection was great.
I made some minor changes on your design (50mm mdf on the ground plus steel foot plates and spikes, singe 22mm plywood baffle and 25mm mdf mid/woofer baffle) and a paint job.  I changed the physical design of crossover also. Please see the attached photos.
Some photos also available on my Photobucket account. http://s1356.photobucket.com/user/guneytuncer/library/?sort=3&page=1
and there are all details available in my blog page (in Turkish Language) http://guneytuncer.blogspot.com.tr/2016/01/bir-open-baffle-macereas-obl15-ve-son.html 
Thanks, Guney
