So a very talented buddy of mine build these a couple of years ago. They are not just K-horn cabs. These are a much better design and WAY more solid. These are about 300lb's approx. anyway he made them very vintage looking I think. He does such nice work with not the best selection of wood working equipment. He's just talented. I will find out which drivers he's using and post back. I just forget. I thinks he using a Radian mid driver and switches between a Stage Accompany Ribbon Driver for highs.He time aligned it and they sounds very nice.Sorry for the crappy pic. They are really much nicer in person.
