Question about speakers series wiring

[edo]

Hello everyone, i'm new to the forum and new to this universe too. I've been playing since i was kid (i'm a kid+ now) but my uncle always provided amps for me so i never digged into this until now.
I've read few guides and i think i got some things (impedance, etc.).
I did not get if both in series and in parallel both speakers (in a 2x configuration) receive the same signal from the amp simultaneously.
I'll try to explain this using the example provided by a guide from Koch Blog:



In series, the signal goes first into one speaker and then into the second, right?
If so the second speaker receives an alterated signal than the one entering into the first speaker, right?
How the signal differs? (does it get lower or higher or what?)

I'm asking cause i am curious about speaker distortion.
I've read that Celestion Blue VOX AC30 are wired in series. Being 15w speakers they do distort a lot? Or one more than the other? Or how does it work?

For example, if i have a 20w head and a 2x12'' cabinet - one being 30w and the other 15w - does the behavior change if i wire them in series and i change which speaker get the signal first (if there's one who gets it first)?

Last question: what you think about combining very different speakers? Like a Jensen and an Alnico Blue?

Thank you very much for your time and i wish everyone a nice day!

I will explain without any nicety other than hey and welcome.

NO NO NO NO The signal is not altered by any of these changes. Only the load of the speaker set is changed as a whole.

That faucet thing look like an extremely stoned person got his hands on a spigot generator app.

This is ALL you need to know

Series wiring ADDS the impedances.

Parallel wiring DIVIDES the impedances.

16x2 in series is 32
16x2 in parallel is 8

This has NOTHING to do with speaker EFFICIENCY. One speaker might be 96db efficient with another being 99db efficient. You will never hear the lesser speaker standing at 2 meters. The 96db speaker is literally 3db less than the 99db.

My secret is that I don't ever mix speakers. Never. Not for any reason . If the speaker sounds like crap, I get another speaker. Mixing speaker types that are equally efficient won't hurt anything, but it's just a mess.. long story.

Thank you!

You are more than welcome! It's confusing to get started, but it's a very simple thing once you understand it.

The first and most important thing is matching the load for your amplifier output, the second thing is what sounds great to you. There is no problem with mixing up speaker types as long as they handle the output of the amp and the load matches, even if you can't hear some of them.

yes, a part of guitar tone is also a distortion from the speakers..speakers are big part of equation, even more important speaker is nothing without the good box, people are not even taking this in account, considering cabinet-as is. cannot be more false.

so VOX AC30 having 30W divides power at 2x15W speakers. some speakers sound best at the limit, here is Celestion Alnico blue, but even better Celestion G12M, pushed to the max, gives sustain, presence, drive, it gives all!

[Reeltarded]

^^^^ That.. so many things to account for. You have to build a philosophy of output drivers.

AC30 is a great design to examine. The combo box is more than half of the sound. An AC30 head into the extension box does not sound the same, especially to a microphone..

Thank you very much guys!
Have a nice day.

There is a minor, perhaps trivial exception. I hesitated to post this, as the original poster is new to this, and I didn't want to confuse the issue.

To a first approximation, it makes no difference, as Reeltarded says. Same voltage across the speaker, no matter how it gets there, same sound out.

But the speaker isn't a simple resistor/capacitor/inductor setup. It's a mechanical device and the cone, air loading, and box resonance make a mechanical resonance that the speaker voltage and current try to control, with varying degrees of success. So anything between the amplifier and the speaker can, maybe, might change the balance of the highs, mids, and lows - the tone - of the speaker a little. This isn't a big change, but people with microscope ears might detect it. If you don't have microscope ears, ignore it and hook them up series or parallel, as long as the amplifier sees the same impedance.

Good to know! Thank you!
Have a nice day.
