[quote name='BassTractor' timestamp='1470137697' post='3103476'] Chris just told you that it WILL run at a 2.67 Ohm load (unlike the TFB550). You do not need any protection. In fact, adding what you think is protection will probably be adding a risk because you do not know what you're doing. If your cabs have the same drivers, then connecting both cabs is one of the best things you can do. As I wrote: the amp "sees" three identical drivers, which is good. The official specification of the TFB750-A - - - and this is written in its user manual, which you should have downloaded - - - is that it delivers 750W into a 2 Ohm load, 630W into a 4 Ohm load and 305W into an 8 Ohm load. As this amp has output transistors (not an output transformer) and can deliver into a 2 Ohm load, it will happily relax with a 2.67 Ohm load.

Cabs are bergantino cn212 and cn112

yes I know that is great amp, that's why I want to keep it. It would be nice to use both cab but I do not want to risk, so I prefer to be safe if there is nothing to insert as a protection

it is Thunderfunk TFB750A

mmmm actually I am satisfied of my rigs... so, I think that best could be use just 212 and in some other case 112. Thanks

Hi Guys, I need an help to understandi if it is possible to use two cabs with different impedance without problem in head amp. I summarise situation. I have one cabinet 2x12 with 4ohm impedance and one cabinet 1x12 with 8 ohm impedance. I have used one by one so far but in case I would like to have a rig with both how to do? I mean is there any device suggested to put in between cabs or amp that allow to connect both at the same time without any risk to damage head?
