Speaker Cab Resonance...How to stop it?

[soundchaser59]

I never have this problem when I play thru my amps and their internal speakers, only when I play thru external cabs. Doesn't matter which cab or which amp, it's always the same resonance....

I get a nasty resonance at about 110hz, the low A to low B area on the guitar. Doesn't matter if it's closed back, open back, 2x10, 2x12, 1x12, Twin, Traynor, Vox, Mesa, no matter what I do I get this resonance. But never when I play straight thru the amp with no cab. And all different types of speakers are involved here, Weber, Jensen, Celestion, Eminence.

How can I avoid this? Or at least reduce it? Can I do something to the cab, or inside the cab to diminish this? Why does it do that with cabs but not with the amps?

Is it because the cabs always sit on the floor, while I always put my amps up on stands??

Don't hate the resonance, embrace it!
Try shifting your EQ around a bit. Is it happening only with one amp or with all amps you try? If only with one, it may just be something you'll have to live with.

Are you using a 7 string-as you refer to the low A to low B? If so you may need to get a 15" speaker to handle that low end.

Like I said, it doesn't matter which amp or which speaker cab I use. I already play with the Bass tone cut almost completely. Live with it? Let the speaker cab win? Not a chance.

Low E string on a 6-string guitar is 80hz. The "low A" (5th fret) then is the 110 hz I mentioned. EQ is not the answer.....or, I should day I do not want EQ to be the answer. I get the tone I want coming from the amp, it's only when I switch to an extension cab that I have this problem. And I dont record the amp, I keep the amp with me next to the mixing board, and I plug into a cab that sits in the (homade) mic booth, and it's the cab that gets recorded. I like to be able to tweak the amp settings while the speaker is mic'd, without having to get up from my chair and walk away from the board.

I'm going to try "de-coupling" the cab from the plywood base it sits on (in the mic booth) by setting the cab up on a small stand or on top of a 6 inch thick piece of foam, or something similar......anything to stop it from resonating with the plywood. I'm hopeful that the plywood base is the real cause of this problem. I'm gonna try that in just a few minutes......
