Hey Everyone,
I have a Trace Elliot AH200 head and an Ashdown 4x10" (8 ohm). The head has 2 speaker outs so I want to connect my other cabinet, a Carvin 18" (4 ohm) as well. The head is built to run two 8ohm cabinets for a total of 4 ohms...
So will connecting both damage my amp ?

not sure what it will do... but it wont be 4ohms... I wouldnt do it

I understand it will the less than 4 ohms ?

You will be running at 2.67 ohms.

Most likely you will encourage your amp to give up the magic smoke.

(impedance of cab 1 X impedance of cab 2) / (impedance of cab 1 + impedance of cab 2)

For instance, if you have a 4-ohm cab and an 8-ohm cab:
multiply 4 x 8 = 32
then 4 + 8 = 12
32 / 12 = 2.667 ohms

bad juju for Trace Elliot , unless Trace Elliot can run 2-ohm

What difference would it make daisy chaining them ?

It will be 2.67 Ohms

Can your amp handle a less than 4 ohm impedance?

Thanks, that link cleared things up, but what about daisy chaining the two cabs ? Will I still get the same resistance?

danke
I believe that a load is a load, so 2.67 ohm parallel or series. could be wrong, but i dont think i am

you can't use a 4 ohm cab without damaging the head. You could keep an eye out in the classifieds. I see eminence 8 ohm 15" neo's for sale on a regular basis.
