Another cab impedance question

[bassace]

I’m off to a double bass gig early Sat and might need a bit of extra firepower. So I’m taking two 10” cabs under a Magellan 800. But one is 4 ohm and the other 8. Amp will be OK because it has a 2.6 ohm outlet. Which cab is likely to be the louder? In other words will one of them overwhelm the other?

Comments much appreciated

The 4 ohm cab will get 2/3rds of the volume and the 8 ohm cab will get 1/3rd of the volume.

Aye, you won't be able to tell the difference, other than the cabs sounding different. 

One cab would need to be taking 10x the power to sound twice as loud, not 2x.
