I completed these speakers 2 months ago from the Jantzen Audio kit. Made with 25mm mdf and veneered with the rather beautiful birds eye maple. Excellent sound with the mid and highs particularly transparent. Turn them up and they sound fabulous. Here is a link to the Troels Gravesen page: http://www.troelsgravesen.dk/FUSION.htm These are heavy speakers so collection only from near Bedford. I’m selling them to fund another kit!
