I'm getting into my first set of MT122s and the plans indicate the rear panel should be removable. How did you accomplish this?

It's all on the plan. Removable panel which bolts onto the battens that go round the sides.

I don't see any battens in the plans? Unless you mean the shelves that hold up the wood horns?

No, that plan doesn't actually show it at all.
Look at the plans for X1 etc which do have access panels shown properly - then work out how to implement the same thing on the MT122. The only thing you'll need to be careful of is to make it wide enough to get the 12's in as the back of the cab isn't all that wide. HTH, David.

Thanks DMorison, I can work out how to make the back removeable/mountable, just wasnt sure if there was a preferred way.
Does the panel need to be sealed with anything? Is it important to be airtight on these cabs? I've only built subwoofers before, but It doesnt seems like the actual cabinet space is important for sound on the MT.

oops, sorry, my mistake about the battens on the plan. when i built mine, i drew out the plans myself in CAD for how i wanted them and worked off them.
the panel should be airtight yes. |

thanks y'all. Have any of you built the MT122 specifically? I have some questions about assembly order.

Those look great! Build pics would be super helpful, all of the old threads seem to have dead pics.
What order of operations did you follow? I'm thinking of assembling the wood horn separately, then putting the sides/top together with the "shelf" inside, then putting the horn in after that. My concern is that if I'm off by a few mm assembling the cabinet that the horn wont fit right.
With the horn - Do I see that you used a temporary "backplate" at the rear to help assemble it? |

sorry i don't seem to have good photos.. it was a good while ago now that i did these. so yeah i think i assembled the whole horn and then fitted it to one side, and fitted the other bits, fitting the other side last. i rebated the side.. don't know that it was neccessary or really gave any advantage though. |
