Had a few vacation days to use and have had this in the back of my mind for a year or two. Had everything laying in my spare parts room, only had to buy the glue for the tolex. The box was an old storage box I made years ago out of 3/4 BB, so I gathered up all the parts added a baffle board and a port and this is what I ended up with. The box to port dimensions aren’t optimized for the speaker but I does work well with the other cab.I wanted something to do more than anything,and it just happens to fit under my sl 210.
