If you want to get the same volume from a 4ohm and 8ohm cabinet you have to use the ONE1400
But each speaker being 8 ohms would have equal power going to it, so if the amp can handle the load, a perfect balance of power to each speaker!

I probably didn’t understand your question. If you use two cabinets with different ohms the two volumes will be unbalanced at the start, even if the two cabinets have the same watts. If you use two cabinets with the same ohms the volume that the header sends to each of the cabinets is the same.
The ONE800 has only one power amp and you cannot decide the volume for each of the two connect cabinets. With the ONE1400, having two separate power amps you can independently decide the volume of each cab.
He wants to drive a 4 ohm AT212 and an 8 ohm AT112, which means if the amp is good down to 2.67 ohms each speaker will get the same amount of power and will produce the same amount of volume (each speaker, not each cab).
In this specific case yes, each speaker will have the same volume. My speech was not related to the individual speaker but to the cabinet in general. A 4ohm cab will have more volume than an 8ohm cab.
I was really just asking about the one800 working at 2.67 ohms. I have an AT112H and and AT 210....both 4 ohm cabs. I use them with a Mesa D800. I have a One1400 on my radar for future backup/alternative amp...just curious. The One1400 has 2 x 700 watt amps.....are they different power amps from the One800 with is rated at 800 watts? I thought they would he the same amps, but a 100 watt discrepancy in power rating?
In order to optimize the project, we preferred to have 800watt supplied if only one output is connected and 1400 (700+700) if both outputs are connected.
I had an issue with a Subway 800 moving about on top of the cabinet as it was so light, same with a Bergantino BI amp. Simple solution was to put Velcro on the cab and bottom of the amp (the Subway, the Berg has sturdier legs) Also, if there’s a handle on the side I wrap the guitar lead around the handle a couple of times. So the amp won’t move. Simples!

I use a $3 roll of table placemat from home Depot or any grocery store that I cut to size. . I Leave 1 on my cab at church & keep 1 in each amp case.. No goo or sticky stuff. Never moves..
I have a ONE 800 amp and an AT212 speaker and my feet are fine.
Cabs and amps are difficult to get because GR is having supply issues like everyone else.

AeroTech cabs from GR. Wow
On your link, the picture of that cab looks like it took a hit on the corner.
The protector is scuffed on the edge, and the screws look damaged.

Maybe, or maybe it was a monday morning model.
I just wanted to make sure not more people had that issue as its a lot of money.
I have a question about GR Bass Dual 800 head. In the manual they talk about "operational led" of green light, turning into red, when overloading input. The problem is, is don't see it on my amp. I just don't see any green light functioning as an operational led. Can someone help me? Thanks!
