Please do a vid of some salt on the top, you will see what is up with the top of the cab as clear as daylight and provide almost as much entertainment as an SVT taking a walk.

You paid to have a functional cabinet built. It shouldn't be your responsibilty to make it functional, nor should you be forced to eat the cost of something that wasn't properly built or was damaged in shipping.
From everything I've read, the builder is a stand up guy. He should be willing to make things right with you. |

Send it back to Oatman. He should give you at least a partial refund. The cab obviously has a serious flaw either in the way it was built (bracing) or the way it was designed. Oatman has enough experience so that he should know whether or not a cab design is going to work. If I were him I'd give you a full refund without hesitation. Either way, it is not your fault and I truly sympathize for your situation.

We just had a mega blizzard, so once I can get to a store, I'm going to do as Don said and to put mattress lining in it.
He's been great all along. I have no doubt he'll make things right. I don't want to assume it's bad bracing, I used to be an auto technician, so I have a calm approach when it comes to diagnosing anything: Don't assume the worst, and start simple then work to more difficult solutions.

I think I'm going to buy some mattress foam as Don recommended and line the the cab. If it stops shaking, I'll be happy. I'm going to start simple then work to more difficult. | 1" thick is fine and all, but how TALL is the bracing? That kind of bracing should be 1.75"-2" tall, standing off the inner surface, minimum.

I dont believe this is going to be fixed by more stuffing inside the cabinet.. this will have simply at best some modest impact of the amplitude (Q) of the resonance.
The sheer amount of energy being transmitted into the head indicates to me that the resonance needs to be moved in frequency..
the current bracing ("along the top, bottom, back and side walls") are more for mechanical integrity of the enclosure from an assembly perspective, rather than for control of cabinet resonances.
Seems highly likely that the solution will involve adding internal bracing .. in the form of panel braces, to split or 1/3 the panel size and/or bracing opposing cabinet surfaces like front/rear and top/bottom braces.

However, when I owned my LDS 15/6 I took the 3015LF out of the cab and it struck me that the cab was very well lined with batting. It looked very well done. Its not like those gk MBxx cabs where there is no lining at all.

| | Registered User | | Join Date: Nov 2011 Location: Cambridge, MA | | | Been too busy to really play with it. I added a bunch of batting to the top, and it seems to have fixed it at low volumes.
I think the cab sounds good, so I'm sticking with it.
I may throw front to back bracing and call it good. If it vibrates, then it vibrates. |

| | Registered User | | Join Date: Nov 2011 Location: Cambridge, MA | | | Update: It's all fixed and good. Gigged it heavily recently with no movement. I also put larger rubber feet on the bottom of my SVT head (which it didn't need), instead of the hard plastic feet that came with it. That should help down the road. |
