: What will happen when you run an 4 ohm cab on the 8 ohm side?? Most 2-10 cabs are 4 ohms. Its a no no. I never said that running the 8 ohm cab on the 4 ohm side will cause any problems other than only getting half the available power to it. Response, wanna borrow my glasses? Still a screwy design.

: : With the GK 800RB amp 4 ohms is the MINIMUM load on the low side. Which means you can use a 1=4 ohm cab,2=8 ohm cabs,4=16 ohm cabs. The low side will not be damaged by a 8 ohm load. At 8 ohms the low side puts out 200 watts of power at 4 ohms the low side is rated at 300 watts.

: :
: : : One, If you run both the 4ohm and 8 ohm cab it will result in the amp seeing a 2.67 amp load. I would be hesitant to do that without checking with GK to see
: : : if it will handle it. A GK rep told me DO NOT run a 4 ohm cab on the 8 ohm circuit of the 700 and 800 it will cause magic smoke to appear. TIC

: : : : : : : :
: : : : : What was GK thinking when they designed the 700 and 800 biamp heads. The
: : : : : Woofer amp is 4 ohms. The mid highs is 8 ohms. Most low end cabs are 8 ohms
: : : : : so you can only get half the amp power available to them. Most, not all, 2-10 cabs,
: : : : : are 4 ohm. They can't be run on the 8 ohm circuit which is why I never looked any further at them! Screwy design.

: : : :
: : : : yah i've heard that ... so if i get a 2x10 cab, would that work with my 400rb fine?? or would i start to loose power to the 15"???
I got a 2000RB that just plain kicks ass. Im runn 4 Bag End 15" and 2 SWR 8x8s
and Im not having any probs.
