I am happy to share with you the results of my job - your project (http://www.troelsgravesen.dk/SEAS-3-Way-Classic-mkII.htm
), but with minor design changes.
Photo is attached. Because of space limitations I put them on the wall.
The left is not fully assembled, because I have broken one of the
binding posts M6/27 so I am waiting for another pair.
Thanks for your job.
