Is this even possible? (head > 3 bass cabs)

[mstone564]

Okay, so I have an SVT 4-Pro and I know that this can be used to power 2 separate 8x10's at the same time, but can it power 1 8x10 AND 2 4x10's at the same time?

I'd assume so, but I wouldn't know how to wire it correctly.
Reason I'm asking is because I have an 8x10 and a 4x10 already and if I were to ever upgrade again I would rather just buy another 4x10 instead of selling my current one to help pay for another 8x10.

if both of the 410's were 8 ohm then it would work

Sweet! How should I connect everything?

[BassmanPaul]

With a SS amp you can add as many cabinets as you want as long as you do not fall below the minimum impedance of the amplifier. In your case that is 2Ω per channel. You could run a pair of 4Ω 8x10 from each channel. As our brother from Alabama opined, if your 4x10 is 8Ω you can add a second identical 4x10 to make 4Ω and run without problems.

8x10 on one channel and both of the 4x10s on the other.

So run the 8x10 with the mono bridge cable, and then connect two speaker cables to both power amp outputs A and B into the 4x10's?

And I just realized my 4x10 is 4 ohms not 8... Is there anyway to change that?

[BassmanPaul]

NO. There is no need to bridge. 8x10 to output A. 4x10s to output B. As the amp is 2Ω stable you can run two 4Ω loads on each channel.

Wire it up like this...

Side A: 4Ω 810 / Side B: 2 x 4Ω 410's

If you were to purchase another 410 to run make sure it's 4Ω and matches the one you already have.

8ohm 4X10's.

If he ran two 4 ohm 4X10's that brings it down to 2 ohms.

You could only rewire it to 16 ohms. You're kinda screwed unfortunately.
Unless you got another one and wired it to 16 ohms as well... Then the two cabs would present an 8 ohm load, which would work fine. Or leave the cabs wired to 4 ohms and use a series cable. Same result.
You can't bridge if you use all three cabs.
You'd plug the 8x10 into one channel and the stack of 4x10's into the other.

The amp is stable at 2Ω.

And I believe there is a balance control.

[JimmyM]

An 810e and two 410hlf's? Holy moley! Doing an arena?

[RickenBoogie]

So long as you can do 2 ohms PER SIDE, then connect the 4 ohm 810 to one side, and the pair of 4 ohm 410's from the other side. (deon't mix the 4 ohm 410 with an 8 ohm 410, keep them identical) Use the balance knob to get equal volume from each side, as the side with 2x 410's is running @ 2 ohms, it will get more power. So, balance, and wear ear plugs.

Maybe I'm reading this wrong, but I though he wanted to connect and 810 and two 410's. Since the 810 is already 4 ohms, how is connecting a pair of 4 ohm 410's going to give a 2 ohm load?

It's got dual power amps, right? Are they both 2 ohm stable?

EDIT: Yes, each side can do 2 ohms.

Yes. Yes.

[mstone564]

Alright, thanks guys!
If I can't get anyone to buy my 4x10 so I can find a cheaper 8x10 I'll definitely do this!

Only reason is... Both guitarists have talked about rocking full stacks and I don't want to be left out haha. We're a LOUD metal band =D

[floridagatorfan]

Kustom has an 810 thats relatively cheap. I think Acoustic's aren't that bad either. But who knows how they sound

Ah. The classic "headbangers' volume wars".

"haha" indeed...
