Hmm. That's a good thought on the frames. The fabrication company offered me them free if they could use them for their apprentice training - but then, they wouldn't have the critical pieces of paper. They did however, make an extra set as the project was fairly simple, but a good training project. When I picked them up, he showed me them and I offered to buy those too. He wouldn't sell them to me, not for the quality of the welding , which was good - but for the fact they were 18mm too narrow. The apprentice misread the drawing - and the drawing showed the distance between the pin holes, NOT the distance to the end.
I like your idea of powering each box separately - I have enough spare amps to do this in stock, although they're not Class D, so an extra two amps will increase the weight considerably, but I can probably do it. Driving them from the Midas M32 would be quite easy too. I'll remember this, and have a go.
It does seem a kind of forgotten product, doesn't - and those that have it don't get excited. Maybe just not a wo factor product but a decent workhorse. I'm very late to the game but it does look like a problem solver for this venue.
