Diezel amp output: Ohm question

Please don't laugh at me for the following question:

What is the difference in sound if you connect your FL 4x12 Diezel cab with V30 for example to the 4 Ohm, 8 Ohm, or 16 Ohm output of the amp ?
Of course considering that each time the cab impedance is matching the amp's output.

What I want to understand is that if the different outputs of the amp have different feel / sound with the same cab.

For your information, I tried the same Diezel cab 2x12 RL with v30 in the 8 Ohm output and with the 2x16 Ohm output splited, and I noticed absolutely no difference at low volume.
My ears are not good so I am counting on your experience. :cry:
 
Highest impedance is always better! which is the 16 ohms.
 
Ummmm. I thought you had to match the output impedance to the recommended load on the cab. I didn't think you could just choose. I could be wrong.
 
The impedance of the cab must match the head. and if you double the power you must always half the Ohms
 
No no no don't get me wrong !
Of course the Cab impedance must match the head.

Here is the thing:

Celestion makes the v30 speakers in 16 Ohm and 8 Ohm each.
If I have a 2x12 cab with 2x8 Ohm v30s, then my cab can either be 16 Ohm without split or 2x8 Ohm stereo and 1x4 Ohm mono.
If I have a 2x12 cab with 2x16 Ohm v30s, then my cab can be 2x16 Ohm stereo and 1x8 Ohm mono.

So question is: does the cab sound the same whether I use 1x4 Ohm, 2x8 Ohm, 1x16 Ohm without split or 2x16 Ohm output of the amp ?

I know the question is not really relevant but I am just curious about all aspects of my amp.

Thanks for your replies by the way guys.
 
Knowing AS WE DO that we MUST MATCH output to load, ahem, there is conjecture around varied individuals who spend time with guitars and amps (aka "musicians") who will forthrightly admit, that 16 ohm is nicer to work with than 4 ohm, citing that 4 ohm out/in can sound and feel "stiff" comparatively.

That said, I'm happy with 16 or 8, but I'd have to agree, 4 somehow does feel a bit lifeless at times, although tonally, I'd be hard pressed to note a difference :dunno:

Unc'Mo

...guitar forums, amirite :lol: :LOL:

All else truly being equal, my dumb ears can't tell a lick of difference between 8ohms vs 16, so I just believe the hype...more is better! :2thumbsup:
 
Good shit bro! My next amp would be a Herbert for sure! I'm wondering how it's gonna sound compare to the VH4 tho.

A question of almost biblical proportions.
 
Thanks to all for your replies.
My amp is D-Moll (at the moment...).

I fully believe you guys about Ohms and amps.
But I just checked again at low volume between 8 Ohm and 16 Ohm, I cannot hear any difference at low volume.
I'll check this week end at good volume and let you know if I hear anything else.

Cheers,
 
16ohm out into 16ohm load will use the full transformer winding and generally sounds better to my ears. And by better, it usually seems like the amp is a bit louder and more full sounding and just seems to be more authoritative. But it's a very subtle difference either way.
 
Thanks for the info,
I will go for a 16 Ohm cab for my next purchase...
 
4 ohms feels and sounds a bit weird, but to be honest, if it were a blind test and I was just playing while someone secretly was switching around my speaker impedance, I doubt I could tell.
