Review on KAKAFOTO Extension Section Extender KET C01 by Fred Meeks

I am very impressed with the interior of this speaker. My only concern is that the 3/8-16 threaded bushing on top was too tight. For my application I had to remove the bushing so I could use a 1/4-20 threaded stud. I couldn't get the jack off. With the help of a vise, I destroyed the threads and tried to free them. In the end I completely disassembled the column, put the top column in my lathe and machined the hub. In doing so I was able to see the amazing design of all the innards and see how well it all works on a lathe. This is a work of art but if you have to use a 1/4-20 bolt be careful you might get in trouble.
