I've got an emperor 4x12 staggered vertical, and I love it. Its got guts, its loud, its gorgeous. However. I do want to address vibration issues, and I would like to experience the benefits of adding bracing to an emperor that others have said they experienced. Please don't flame emperor, I like my cabinet a lot, its really pretty, it probably won't be my last cabinet purchase but i don't think I'll ever sell it. I want advice on this subject, not to be told to use a time machine and not buy it. I don't want to drill through my cab if it can be avoided. I've looked at other things here about bracing, but I'm a real noob on this stuff. Where does the bracing go, how do I attach it to the cab's inside if I don't want to drill (if possible), what materials will I need... I looked at greenboy, and I can't yet figure out how to apply his diagrams to a non fearful design I'm gonna keep trying but some basic plain language advice will be appreciated.
