Forgive me if it's already been covered, but has anyone tried running the Hathor 1203 on its side (or two of them as such)? I am just thinking of a lot of scenarios where that could be a better footprint for some amps, but I wasn't sure if dispersion on the mid driver/chambers would be compromised.
Yes, I have used my 1203's on their sides (stacked) several times. And, I'm still alive to tell it, nothing exploded!
Generally, I stack them vertically. When stacked vertically, and using my Monique rack rig, the rack overhangs. That isn't a problem as it is still stable. I don't have a problem stacking them horizontally if needed, but with our stage setup, vertical stacking is not a problem.
I would say, try it. But if you are gigging without P. A. support I would suggest vertical stacking.
Just my humble opinion.
