I just bought a pair of used Scum Back M75-16 hp 16 ohm for a 2x12 cab I have.

Also picked up a couple of Eminence speakers one a Governor speaker,the other a Wizard speaker both 8ohm.

So I'm going to do some experiments with a closed 2x12 Zilla cab I own and see how they fare.

Currently it is carrying a pair of Celestion G12Ms rated at 16ohm each and wired to 8 ohms.

So I want to try a similar setup with these other two pairs to see what is does to my sound.

My attenuator is a Koch 4 ohm unit and my amp, a Ceriatone Plexi clone is a 50 watter amp has 4, 8 & 16 ohm taps.

Any advice on how to get the best out of these speakers would be appreciated. Also what to avoid etc

I know not to mismatch ohms etc but will sometimes use the cab live so the attenuator is really for rehearsals and recording.

Contemplating loading two different cabs for different tones, so any advice on a good 2x12 cab build or maker.

The Zilla is pretty good, but I'm open to experienced advice.

Thank you in advance and I am also using the search function onn this and other sites for tips and good advice.

But I find sometimes its best to ask for help as well.

I am not sure I really see a question here. Sounds like you have everything under control, just need to put in a fair amount of time with the different speakers/cabs. Does your attenuator limit you to a 4 ohm cab, or does the 4 ohms refer to the impedance of the amp?
I can tell you that the Wizard/Governor combination is hard to beat. It works well with a lot of amps and a lot of music. I know you bought your Scums used, but the owner, Jim, is a pretty pro-active guy. Speakers are what makes his world go around, he will be happy to discuss your Scums via email. I would encourage you to give him a shout.
So I do not really have any advice for you. Sounds like you are on top of it all, just need to spend the time auditioning your gear.
Good Luck

My Koch Loadbox II will only do 4 ohms.

So the Eminence is fine as I'll wire them to 4 ohm

However the Scumbacks are getting wired 8ohm, I figure they will be okay. But advice is always appreciated.

Tried amp out last night at rehearsals and it worked for a while. Had used it at home for the last fortnight on a low output setting as well.

Now its silent and has no output, I have changed blown HT fuse this morning and still no sound. Amp lights up and can hear feint mains hum as you would expect. But no sound.

Checked cables and cab, they are both fine.

So I don't recommend setting an amp head to 4 ohm out into a 4 ohm Load Box, then into 8 ohm cab.

UPDATE

So I took the power tubes out, reseated them and now it works?

It had blown the H.T. fuse last night at rehearsal.

But seems to work now.

I'm confused as to what happened, but I'm no amp expert. Have emailed Nik and reported my findings, so hopefully he may have some suggestions for me.

I'm glad it works as this amp screams!
