Hi

Dumb question,

I have a 8 ohm Bogner Uberkab which is mono 4 x12

Would a 16 ohm 4x12 stereo cab sound different or is it just the ability to stack 2 cabs together?

I only need one cab but just wonder on sound.......

A stereo cab would allow you to use a stereo amp and effects.

If you're driving it with a conventional guitar head there's no advantage to having a stereo cab.

I have retrofitted a stereo switch in a Marshall 4x12. It allow me to use it in mono at 16 ohm or stereo at twice 8 ohm. It is convenient, for example when using a POD with a stereo power amp.

I have read something about using a 16 ohm cab on 16 ohm tap for a better sounding amp, the theory being that you use all the output transformer winding, but there is no agreement on this.

Agreement among whom?

Depends on who you ask! Any reasonably educated tech will agree that it makes no difference! You might get slightly less wire losses running 16 ohm head and cab settings than running 8 or 4 ohm head/cab selections. The output transformer will step up the load by the proper ratio to deliver the correct load to the output tubes, regardless.

If the argument is among non-technical guitar players then I agree there will likely be no agreement - unless you buy them enough beer!

Or you may find a tech who appears to favour this theory. It's a sure bet he also has something to sell you...

Wasn't that one of those wacky Gerald Weber theories. Complete junk science

Although given enough beers, I could be convinced.

Something like that. I am unsure if it is Gerald or Ted Weber that came with this theory? I read about it in a Kevin O'Connors book but he did not mention any name. In a section titled "The myth of encompassment", he mention that it came from a guy manufacturing speakers.

So with my 5150 peavey head (which handles 4/8/16) there would be no difference in sound to say a 16 ohm marshall cab to a 8 ohm bogner cab?

There could be a difference but it will be caused by different speakers or different cab construction. Not because of impedance.
