3 Cabinets, 1 Backline 600

m181bass · #1 07-07-2011, 09:49 AM

Alright, there was a similar thread started about using more cabinets than outputs however I feel this is a slightly different question which constitutes a different thread. I am currently in ownership of a GK Backline 600 and I love the head. I am also running thru a similar GK 410 cab. However, the 410 is really hard for me to transport,( feel bad for you 810 guys) so I wanted to get two 210 cabs where I could have either both of them running, the 410 and one 210 or, my issue both 210's and the 410. I only have two speaker outputs, so how would I do this? I would like to stay all gk btw, I just think it would look cleaner. Pictures will be posted below.

Your going to have a problem any way you try to do it.

Your head can only support down to a 4 ohm load. If your 4X10 is already 4 ohms, your done.

If your 4X10 is 8 ohms, you can run another 8 ohm load with it.

However, if you get two (2) 8 ohm 2X10's, you can only run one of them with your 4X10, and your 2X10 speakers will be getting twice the power of the speakers in the 4X10.

If you want to run all three, you would have to get a special "serial" cable to connect the two 2X10's together, giving you a load of 16 ohms. You could then combine that with the 4X10 safely, but your power distribution per speaker will still be screwed up.

The only option that could work is to buy two 4 ohm 2X10's, and rewire the speakers in each cab in series to make them 16 ohm cabs.

The single 2X10 could safely be run with the 4X10, and when running both 2X10's together you would get a matching 8 ohm load for the total of 4X10's to connect with your original 4X10 cab.

His 4x10 cab is only 8ohm. The label is pictured in the 1st pic.

OP, you only have room for one more 8 ohm cab, or two 4ohm 2x10 cab rewired to 16ohm like Pounder said.

Missed that

Then the only real option for safe ohm load and safe power distribution would be to find two 4 ohm 2X10's (that contain two 8 ohm 10's wired parallel), and change the wiring to series for a 16 ohm load each 2X10 cab.

When using only one 2X10 with the existing 8 ohm 4X10, there will be equal power distribution to the total 6 speakers, and you will remain above the 4 ohm minimum.

When using all three cabs, you will be at the 4 ohm minimum, and still have equal power distribution.

As far as connecting it all up, the 2X10 cabs you get would need to have a set of parallel wired connectors on them so that you could run a speaker cable from the head to the first 2X10, and daisey chain the second 2x10 to the first.

My GK 800RB could handle those 3 cabs; maybe you should look into that head.

Get two 210's, stack them vertically, turn off the bottom tweeter, and your rig will rock like a 410 with a tweeter except it will be more present onstage.

+1!
