Most ryder freindly boxes?

yeah world over,  L'Acoustics closely followed by D&B are by far the most rider friendly brands.  (well, western world certainly, maybe not in Aisa etc lol I have no idea)

After that it becomes a little more regional either side of the pond:  in the UK and Europe Martin Audio has a strong showing, Meyer is still in there and then other brands like JBL, EV etc get a smattering of work. However in the US, those brands probably flip a bit, with JBL and Meyer having a much stronger position and Martin, while still being a strong contender, drops down a little. Adamson is up around that level too in the US, and EAW's Anya is picking up steam. 

Below this you have other brands like EM Acoustics, Coda Audio etc. (and I'm sure equivalent local US brands we wont have heard of).  The manufacturer wants to get them some exposure and provides a great deal, so they're picked up by big hire companies as a B or C system to put out for less important things or when their main brands are all out. They get used for events more on the reputation of the hire company itself and the fact that their customers trust that if they say it sounds great for an event that it'll be fine, rather than the recognition of the actual brand of the speakers as most people who aren't into sound and speakers like us won't have heard of them.

I wouldn't have - their subs arn't spectacular and consistency/qc leaves something to be desired when compared to the more established names.
