Mixing cabs

[SteveXFR]

I'm using an Orange Terror head which has two 4 ohm speaker outputs and at the moment I'm using a single Orange 4x10 8 ohm cab. 

I'd like to add a 1x15 cab for some extra bottom end. 

Would the 1x15 have to be 8 ohm as well or will 4 ohm be OK? 

Does it matter whether it's an Orange cab?

Like he said. 115s in general don't add any low end to 410s, and they have lower sensitivity and maximum output. That said, where 410s are concerned the Orange OBC isn't exactly stellar, being loaded with entry level Eminence Beta 10 drivers. I'd be looking at replacing it, rather than trying to augment it.

Your amp does not have two 4 ohm outputs, it has one 4 ohm output with 2 parallel output jacks wired to it. Which is why ...

Looking at the manual, the minimum load is 4 Ohms, so both cabs would need to be 8 Ohms. It will do 1x8, 2x8, or 1x4.

 

... is the formula you are looking for.

It can also be switched to 2 Ohms.

Which Orange Terror amp can be switched to 2 ohms?

It seems my eyesight has let me down there. I was sure the label said 2 / 4 ohms. I just put my glasses on and it actually says 4 / 8 ohms.

Mixing cabs is always a compromise. EQ settings cannot be perfect for both.

 

Sell the 4x10 and get something that gives you what you need in a single cab, and then if you still want more, get another identical one.

Unless they were designed to be mixed. Mesa Subway, Bergantino and my EV loaded Mesa cabs do/did mix. Others may do but you'll have to find that out.

If they don't have a crossover that assigns different pass bands to different drivers they weren't truly designed to be mixed, advertising claims notwithstanding. I've yet to see definitive objective data that says otherwise.
