no replies for a few days, so i'll just say although i've never put them on scales, with pd123er drivers fitted they come in at around the 50kg margin, or there abouts.
odd centre of balance so flying them might be a bit awkward. |

dont forget they you will need to provide additional support to cabinet joins to spread the load presented by the weight of the cab - it is not acceptable to rely on the pannel joints alone if the weight of the cab, and possibly subsequent cabs is passing throught joints
this is usually done by internal metalwork, and should be engineered and designed to be able to carry at least 6 times the weight to be hung.
This is a complex area with many potential issues, so tread carefully

flying DIY cabs is a big no-no!! need properly designed flywear fixed to the correct points of the cabinet to make them safe. If using your own flying hardware, then that too much be destruction tested by an engineering firm and to do so costs mega money. Be much better off - safety and cost - just to go buy some decent used cabs similar.

I wouldn't say you can't fly DIY cabs but I guess it's like electrical stuff where if you need to ask how to do it, you shouldn't be considering it!

I only asked the weight of a finshed cab for some draft calculations, not how to fly Some very interesting points discussed here... thanks What I'm actually looking at is a skeletal version of the MT121 for flying This will reduce weight and also all the cab related issues when flying Thanks for all your input guys. |

if you mount the horns in a welded frame made out of steel box section you should have absolutely no problems with safe flying.
I would be more concerned if you are intending to use aluminium but this is not to say it can't be done properly.

@all:
any1 seen a d&b q1/7/10 open? there is no internal framing for horns etc
...and you can hang up to 3 units on the standart flying point (on top of every q housing) with their Z5156 adapter... go figure!
