HEAD/CAB not getting along

[Rickenjosh]

Hey,
So I recently (tonight) picked up a SVT CL head to use with my Orange 4x10 cab. The head only runs on 2 or 4 ohms and the cab is rated at 8. I know some people will say run it the way it is, but I really don't want to do that. Is there any way I can make these two get along?

Get another 8 ohm cab. 210, 410, whatever.

Buy another 8 ohm cab or have your Orange rewired for 4ohms.

I have used a SVT with a single 8ohm for an entire gig (2nd speaker wasn't plugged in) and my SVT was fine, but I would strongly recommend not doing this.

 

[Rickenjosh]

Yeah that was my first thought, However I don't have any money right now or need for another cab. anything else I could try?

 

[Rickenjosh]

What about rewiring the 4x10 to 2 or 4 ohms is that possible/easily done?

Depends on the cab's internal wiring. If it uses a series/parallel wiring scheme you might be able to make a 2 ohm cab out of it.

 

[Rickenjosh]

would that change any of the characteristics of the cab?

No. The speakers used in the cab would have to be 8 ohm impedance though. Only way 4 speakers can make an 8 ohm cab is four 8 ohm speakers in series/parallel or four 32 ohm speakers in parallel. If 32 ohm you are done, no changing.

No, but you do need to know what you're doing, or you could short it out and kill your SVT. First thing to do, is figure out what's in the cab, and how they're wired. Short of that, be more careful when buying gear- do the research before you buy.

I know the cab has Eminence Beta 10A which are 8 ohms., and the head fell into my hands .... 400$ I couldn't say no. I usually am smarter with my gear purchases but I was amp less

If you are sure they are 8 ohm speakers then wire the four speakers parallel (+ and - goes to each speaker) and you will have a 2 ohm load for the amp. Chances are the top two and bottom two are wired in series right now. You'll need to add four wires total.

an SVT classic head for 4 bones?

sounds pretty smart to me!

with 8Ω speakers, you can actually wire that cab with two jacks, one for 8Ω and one for 2Ω.

that way it's still useful paired with another matching 4x10 cab (what you really want to make that SVT rock) but you could use it by itself if need be.

 

[Rickenjosh]

Awesome! Ill give it a go

How much smarter does it get than a CL for $400???

.

How do you pull that one off?

I can't see it working without a switch, which is risky for the SVT. It could wind up in the wrong position and you might not even notice. If it failed open, poof goes the amp.

marshall guitar cabs routinely come that way.

you use those big black plastic cliff jacks, which have extra switching contacts to make it happen.

Yes but the switching contacts inevitably lead to problems down the road.

have your Orange rewired for 4ohms.

there is no way that an 8Ω cabinet can be rewired to 4Ω
