I think I found my cab...

[Rex_Rocker]

He could sell/trade off those greenbacks and put some 8ohm V30's, K100's, or something really sweet in there.

That's exactly what I did with my 1960ax when I got it, traded the greenies for some V30's or T-75's if I remember correctly.

Downgrade.

I kid I kid.

He's not going to blow anything. The amp will be darker with less punch. Might be fine for rock and classic metal.

I wouldn't get it myself because why pay foe something that ain't quite perfect when there are plenty of 8ohm cabs out there, plus I play in the death/thrash/black realm almost exclusively (unless I'm in the mood for trippy/erie phased/delayed/reverbed cleans),,,,,,so I want max punch.

I know that an Amps output in Ohms, needs to see that much or MORE on the other end.

So 16 into 4 cab, yeah....that's a bad idea. But 8 into 16 - not a problem, electrically speaking.

I know you do.

 

[jeremy]

ideally it should be matched with a tube amp, but 8ohm out into 16ohm cab wont hurt anything as long as the trannys are well built. as others have said, might sound a bit different though

Thats like saying "i just do a [little] Heroin everyday".
If impedance mismatches were "no big deal" then there would be no need for "correctly matching impedance"
Ever stop & think how many naïve folks reading your post might smoke their output transformer ?

You could rewire the cab in parallel that would make it a 4 ohm cab.

He is running 8 ohms into 16 ohms, he will likely have no problems. Output transformers fry on perfectly matched amps also, don't they? It all comes down to your personal tolerance of risk. I do not see any information Aceman posted that is untrue or misleading.

I think your insinuating a Mesa head with only perform optimally with a Mesa cab is more misleading and confusing for a noob than anything Aceman posted.

Just for some additional color on the speaker ohm discussion... back when I bought a Heritage Greenback 20w/25w, I noticed that the ohm rating was 15 ohm, so I contacted Celestion to understand what was going on and make sure I was wiring it up correctly. The response from Celestion was that 15 ohm is just what they put on the originals back in the day and not to take it too literally, because in fact the actual ohms the amp will see from the speaker load will vary by frequency. The ohms stated on the speaker is just an overall average. Generally, you want to match things up so they perform and sound their best, but it is possible to have a mismatch of lower at the amp/higher at the speaker and still function, but it likely won't sound it's best and can, in some amps, shorten the life of certain amp components. YMMV

Ever stop and think that you could actually contribute something meaningful and clear?

SHOW ME THE EVIDENCE that an 8ohm into a 16ohm cabinet will be a problem for my Mesa.

Better yet - just post a picture of your gear. Thanks but no thanks.

Feel free to either comment on this specific situation, or go post the definitive series of jpeg's for newbs on Amp/Cab matching.

but it likely won't sound it's best

Depending on what "best" means to you. My Mesa is pretty bright and I run ceramic screamers mostly, so darker is not a bad thing necessarily.

Too sensible!

 

[dave74]

Try it both ways. First stock at 16ohms from the 8ohm tap,,, then rewired to 4ohms from a correct matching 4ohm tap, then be joyous that you rewired it.

FWIW when I was talking to Celestion, "best" meant "as the manufacturer intended and tested for."
Obviously, there is latitude to do what you need to troubleshoot other issues you might be facing.

This is an intriguing option....

 

[dave74]

Better hurry!!! I bet he's had some offers.

 

[chadd]

I need to move to a tiny house on a small island...

Those start around $1.5M down here. Even selling my house up north won't put me in a position to buy something for a while. Tons of stuff on the market right now, too. I guess a lot of folks are seeing the prices and deciding to cash out.

So, let me ask this; What kind of wiring wizardry would it take to turn that cab into an 8ohm cab?

*And fyi - I really like the idea of whoever said go 2 Greenback & 2 whatever is in my MX cab, and drop the other two greenbacks into my 2x12....

Install 8ohm speakers wired in series/parallel. You're not going to get 8 ohms out of 4 16 ohm speakers.
