I had the laptop volume maxed and the Amps pre and post at 12.
It sounded like the intro to heavy friends the rising low end hmmmmmmmmmmmmmmmm
It was shaking the house. Did I do it wrong? Or was barefaced posting the wrong frequency for 25Hz?
Maybe I am wrong saying it was farting, but I've never had a Low E sound like that. It was maybe chuffing? It was just broken up sounding and didn't make much bass like it was struggling.
I have read these MBE cabs don't have dampening material and some years had less bracing. Could it be I am hearing the freqeuncies getting chopped up by the undampened walls?
Also I was using the active EQ and had the Low mids boosted the full 15Db if that changes things.
