Hi, this is my father's Altec Stonehead DIY project.
He is 50+, and a litlle crazy in the head (I thought for a long time).
We experimented with differend drivers and crossovers for nearly a jear, build a pair of nice cabinets, and so here we are. The top is made of Belgium Granite.
For LF we use the Altec 416-8b, for mid Altec 808-8b with Stereo-lab 500Hz horns, and for HF the JBL 075 ring radiator. They sound pretty good.
