16 ohm or 4 ohm?

I don't think it matters at all as long as you keep the head and cabinet set to the same output load. With a 16 & 4 ohm choice, just don't mismatch them.

 

Higher impedance often is prefered for some reasons. More winds and iron, less loss in cables... equals more headroom. Then you may not prefer the tone of the 16 ohm mode of the cab or the 16 ohm wind. I believe the speakers are in series and you won't get the smoothing effect with the speakers in series.

 

The only real difference is the speaker cab will either be series at 16 ohm or parallel at 4 ohm. Try both. You prolly won't hear a difference. If you do, pick the one you like better.

 

I have all my 212 cabs with 8ohm speakers and wired so I can run them on either 16ohms with the speakers in series or 4ohms with the speakers in parallel. I only have a few amps with the ability to go from 4, 8, and 16ohms. When given the option, I go with 16ohms. I found at least with my Marshall 2553 that I like it better with the cab at 16ohms.

Parallel gives a cleaner overall sound think Fender

Series gives more damping and a crunchier tone because the speakers are loading on each other think Marshall.

With my Marshall style head I run in series at 16 ohms, I should try 4 ohms just to see but am not that motivated as it sounds good now.

One thing however, if you blow up a speaker when wired in series you can really damage your amp as you have created an open circuit. In parallel one speaker will still be working.

 

Using the 16 ohm tap on the amp you are using the entire transformer, as it was designed. This will give you bigger, deeper bass, more headroom, etc..

 

Look at Fender amps and you decide. The transformer tap matters little, it's how the speakers are wired.

 

I just read a mesa boogie manual the other day and in it Randall Smith states that tubes will last longer with a 16 ohm load

 

Depends on how hard you drive the amp, really. Some amps were designed to be run with a certain load to sound their best. Though the tonal differences may seem small they're still there. Maybe doesn't matter much for the hobbyist I know more discerning guitarists have their favourite taps and wirings.

 

Curious, Matchless and Badcat 212 combos all come with 8k speakers wired for a 4k load. Why is that? Those amps have extra outputs for more speakers but the way they come wired you can't hook up any more speakers or you would cut the load down to 2k. I think its strange that they assume anyone that would buy one of their amps would know this.
So why do they wire them to 4? Will the amp run its best this way?

 

One thing to consider. If you going 16 ohm you have two speakers in series. On blows and you lose both and you end up with no load on the amp. Could be possibly harm the amp. If you go 4 ohms you're in parrallel and if one speaker blows the other is still there to take some of the load.

 

Pretty sure he was referring to running a 16 ohm mismatch vs a 4 ohm mismatch on the 8 ohm tap.
Not an endorsement for 16 ohm straight up as a tube life extending strategy.
Pretty sure. . . Best check that one. .

 

this thread is a serious misinformation risk. OP, you'd be better off calling up one of the smaller cab/speaker maker friends of TGP like Avatar, Weber, Scumback, WGS, etc. they are all super cool stand up folks and very willing to answer any question. or just ask Egnater, if that's not too obvious.

then come back to this thread and correct some of these wild claims.

 

This is something I have thought of for sure, but when I think my amps sounds better with the speakers in the cab in series and the amp set at 16ohms, than that trumped the safety for me.

 

that's interesting as I find the opposite to be true!

I have several heads that can be run at 4/8/16 and a cab that I built with two 8 ohm speakers that can be run in parallel for 4 ohms and series for 16ohms. I've always found the 4 ohm load to have more headroom, more power, more punch, more low end and more clarity. The 16ohm load is smoother, darker, more compressed, less open and big sounding. Of course we are talking fairly subtle/minor differences here but that's the way I hear it.....
