Title: Plugging In Extra Cabinet -ohm? Post by: TommyTone on December 26, 2009, 11:53:17 PM If I two (2) 8 ohm 1x12 cabs. Do I plug first cab into "Main" and second cab into "Extension" and set at 4 ohm??
What are pro's and or con's you have found with using 1x12 against 2 1x12's? Thanks!! Title: Re: Plugging In Extra Cabinet -ohm?

And, yes, if you connect two 8 ohm cabinets to the amp, you should switch the impedance to 4 ohms. Title: Re: Plugging In Extra Cabinet -ohm?

Title: Re: Plugging In Extra Cabinet -ohm? Post by: lions den on March 17, 2010, 04:21:12 AM If you select a higher impedance on the amp that what you have connected, you don't get efficient power out of the amp, and could damage your output transformer. If anything, always match things up or worst case connect a speaker load that is higher than what your amp is set for, but never the other way around. For the other question, the benefits of having 2 cabs over 1 is moving more air. if you're in a bigger room it's great, if you're in a small space 1 should be ok.
