HelloThis is my story of how I went when I wanted to build the ultimate bass amp.Here is the story of “Tower of Power” as they were baptized rather quickly when the project was revealed among the local DIY community.First of all I wanted two dedicated mono subwoofer amps that bettered the Crown K2s they were to replace.After having read and heard a lot of positive stuff about these Aussie Amps, I felt they fulfilled my pre defined criteria very well.Class AB, high power, high damping factor with many output devices and what seemed to be good quality parts.Second I wanted an unusual design, that also limited the floorspace needed, since my livingroom was already crowded by horns and and electronics.After a lot of research I landed on building a pair of Holton 800s, but in a vertical arrangement instead of the classic rack style cabinetBy coincidence I came across...
