i want to power two 4 ohm cabs

Anything that says 2 ohms on it.

 

Or a two channel power amp that can handle 4 ohms per channel.

I run a pair of 4 ohm cabinets in series for an 8 ohm load.
I bought a funky T shaped speaker cable.

My main rig is a tube head, so I'm not really loosing output with it this way... for my backup, by going from 4 ohms to 8 I'm going from 1100 watts to 900 watts... still MORE then enough.

 

Any two channel power amp with separate preamp will do. Example: I run two 4 ohm 4x10 cabs, each one on a different channel of my QSC PLX3002 power amp.

 

My cabs are all 4 ohms. When I need more than one cab, I just use an additional amp (Thunderfunks). Having said that, I'm going to be giving one of those Speakermate things a whirl soon. Just waiting for it to get here....

 

check this link
one other tb member made a great list of heads that woudl power 2 ohms and i cant find the thread

The thread you referenced does, itself, include a link to the dude's list of 2 ohm stable heads.

 

Does great at 2 ohms

 

How are you doing that? Wouldn't 4+4=2 ohms? Thanks

 

the cable he's using hooks the cabinets up in series rather than parallel. 4 ohm and 4 ohms in series is 8 ohms .

 

I am really interested in this. I want to make sure I understand. James is coming out of the power amp, into one 4 ohm cab, out of that into another 4 ohm cab-right?

 

Ampeg SVT 4pro
Ampeg B4r
Hartke 7000
Carvin R1000/600
all have stereo power amps that will run one 4 ohm cab per side.

 

no that's a parallel conection
special cables are required when using the parallel outs on cabinets and amps to make a series connection

 

Here's the link to save you paging through the old thread.

 

I got a cable from http://www.procablesnsound.com/

it's a big "T" made from 12 gauge wire with 3x 3 foot legs. 1/4" connector for my Peavey tube head (and a 1/4" to speakon for my bridged Crown), then a speakon for each Schroeder

cost me $50 with the adapter and shipping

I caught the link to procablesnsound from Henry (fellow TBer and Benavente and Schroeder player like myself )

 

I only got the speakon because my cabs have that option. having all 3 connectors 1/4" would make it a little cheaper I think.

What does your head put out @ 8ohms? Some heads will loose to much, I was lucky that my poweramp is still 900watts at 8ohm bridged... and the tube head is the same at either 4 or 8 ohms

 

Hey James, I just tried out a 1/4 version of the cable you suggested (TFB-420 into two 4 ohm WBS 2X12 cabs). A local shop here made one up for me, and it only took about 15 minutes!. It actually works great!

So if my amp is now "seeing" 8 ohms, I should be able to run a 3rd 4 ohm cabinet in parallel to make the amp operate at 4 ohms again, right?

Boooohhaahahhahahaha!!!
