At practice today, i put my avatar 2x10 sideways on top of my hartke combo 1x12. i was at least a 1/4 turn less on my volumes than i normally am. all just by raising up my speakers to ear level. i had the hartke on and then turned it off and i couldnt tell a difference so i left it off but kept my avatar on top of that. how do you guys raise your amps? i know there was a post about this but that was more, tiilting them, not lifting them.
