My knowledge tells me that in the same scenario I would want to mix a 8 ohm 2X10 with a 4 ohm 4X10. That would provide 33/66 split between the two cabs.

I promise you, in this case The 2X10 would not be heard out on the dance floor the 4ohm 4X10 would completely over power it.

How do you figure? If the drivers are the same in the 210 and the 410, how is this not exactly like using a 610?

Are you saying that there is no advantage to running a 610 over a 410? and therefor no advantage to running a 410 over a 210, or an 810 over a 610?

In this case the 2X10 is drawing a lot less power than the 4X10. In the case of a 6X10 the 6 drivers are getting equal power.
Your typical 6X10 is 4 ohm. Now imagine that cabinet wired in such a way that 2 drivers were wired at 8 ohm and then the other 4 drivers were wired to be 4 Ohms. The 2 drivers would not be as loud as the other 4. Nobody would wire a cabinet in such a way.

In the same cab yes there is, in two cabs maybe no. See above.

Unless the 2x10 is 4ohm and the 4x10 is 8ohm

In the case of an 8 Ohm 210 and a 4 Ohm 410, all six drivers are seeing the exact same amount of power...

You dont even know what you are arguing here...

I completely Disagree. You can open the user manual from just about any bass amp and be proven otherwise.

You just argued both sides of an argument.

If you have a 210 that is 8 Ohms, and a 4 Ohm 410 1/3 of the power goes to the 210, and 2/3 of the power goes to the 410. So 1/6th of the power goes to each speaker. Each driver sees the same amount of power, so each is heard equally.

How? A 4 ohm 6X10 typically uses 24 ohm drivers, but if there's one that uses 3 ohm drivers you still can't get to 8 and 4, and if you did it would no longer be a 4 ohm cab.

walterw · #51 01-01-2013, 08:02 PM

yup, it's not even a question.

8Ω 2x10 plus 4Ω 4x10 equals all 6 individual speakers getting equal power.

If I were to hook up these cabinets to my Hartke lh1000. Here's what I would get. 225 watts to the 2X10(8ohm) and 320 Watts to the 4X10(4 ohm). I guess that's where I'm getting lost. I just can't see the 2X10 being near as loud.

That is if you hooked them up one at a time. The total impedance of an 8 Ohm cab plus a 4 Ohm cab is 2.666 Ohms. Many amps are not 2 Ohm stable so they can not run this combination, but for those that can they will send equal power to each cab.

If you have a stereo power amp then you may get different distributions of power, but you can balance them with the attenuators.

In my case it's a question. My amp would be putting 225 watts to the 2X10 and 320 watts to the 4X10. So how exactly is the power being divided to make all 6 get the exact amount of power?

That Hartke is a two channel amp.

Its has a dual mono operation? with no way to balance the power between channels?

Yes this may be the case. As I have said there is no way to balance the power to each channel? IMHO that is a weakness of design.

NYCbassist · #57 01-01-2013, 08:21 PM

I can balance the 2 channels. With my 1X15 and 2X10(both 4 ohms) It sounds best with the Balance Knob in the middle.

There is a balance control for dual mono operation and the user can tailor that balance however they see fit.

Then balancing between an 8 Ohm 210 and 4 Ohm 410 is just as simple...

**CL400Peavey** · #60 01-01-2013, 08:25 PM

So dual mono set ups aside:

Running a 4 Ohm 410 and an 8 Ohm 210 on a 2 Ohm stable amp, will split the power equally between all 6 drivers.
