I can just put it down the middle of my sub and have the sub resting on top of it. That should be fine right? As long as the sub is physically off the floor it doesn't matter if it overhangs the Gramma about 6" on each side?
That sounds like a good plan. The corners are braced and less able to resonate.
That one fastener that would not go any tighter might have been tight enough as opposed to stripped.
I just watched KFP2 and when the 'skadoosh' seen came I turned everything down because of my condo dweller status and then I rewound it to let it play at normal volume after it didn't tear the walls down. I don't think my subs can reproduce the frequencies being used in that scene. It didn't seem crazy at all. There was a low thump and I figured the subs were trying to say something but their LF Kung Fu is weak. I'm sure it doesn't help that the frequencies that they can't reproduce worth beans I EQ'ed out of the signal to give them a chance to do everything else better and I employ the infrasonic filter on my EQ. Lame, huh?
Did tightening the fasteners ease the cradle rock? I can't imagine the decoupling affecting the rattling of the objects in the room but did it make the bass
sound better?
