Is the Powerhouse 4x10 cab efficient enough with a Carbine at 8 ohms to be powerful enough in a loud rock / alternative band situation? I've called 5 different stores in two different states and all the Mesa 4x10 they have are 8 ohms. I went and try this combination and it sure seems pretty efficient for an 8 ohm cab. In fact it was louder than another Aguilar 8 ohm cab. And if I'm not mistaken, Mesa used to only offer 8 ohms cabs not long ago right? Any of you have experience with this setup and what are your thoughts? Thanks!
