MTH-30

where the cabs sitting on the stage, or on the floor infront of the stage..... and was the stage constructed with a wooden floor or a concrete floor.....

yes lots of shaking! it was a complete blunder not installing wooden mounts for the grills, but i was in a rush. they will be changed before their next outing.

It was a portable (wood with alu rigging) stage, around 50-60cm heigh. The subs were placed right next to it, with front of the sub in line with front of stage...

it could of been rearward base waves echoing under the staging..... Ive heard this issue when ive see people putting there subs on the stage area.

That was with two cabs, 4 should give more. Caused by the horn effect? Is this familiar to anyone?

Hi. Answer is boundary and cancellation modes. This subs behave like horns, except there is nothing to be gained by extending horn path. Good explanation can be found here: billfitzmaurice.info/forum/viewtopic.php?f=1&t=398

The overall dimensions of the MTH-30 seem to be 68 x 34 x 57.7 cm.
According to the construction plans the outer panels are included in those dimensions.
However, the width of 34 cm can't be right, because the 12SB30 won't fit in a space of just 31 cm.

What's the matter with this? Is the overall width 37 cm while the height and the depth are correct?

Help me out, please!
Thanks! smiley1

The overall width is 37cm, while the height is 68 and the depth is 60,7 (All with 15mm thick panels).

Okay, thank you!!
So the description is not completely adequate, I assume.

And I suppose you are sure about it, having built at least one, but the depth is 60,7 yes?
When I look at the construction plan, I can't find external panels to make the depth 3 cm larger than the 57,7 cm.
For it says the height is 65, but then without the top and bottom.
With the depth it really says 57,7 when I look at it

the plans are correct. outside dimensions of the cab are ...depth 57.7cm width 68cm and height 37cm

Sorry, i've made a mistake !
The external depth is 57,7 and not 60,7 smiley2 .
