Hi everyone,
I'm adding a second 12" cabinet to my Maz 18 mkII combo, creating a punchy mini-stack. Both 8 ohm speakers. I have a choice of series or parallel, which does influence the tone, and a choice of running 4 or 16 ohms, also a tone factor. I know the type of speakers plays a huge role here, but this is not a variable for now.
Anyone tried the wiring and impedance variations? Any preference?
Thanks for your comments,
Swampcooler

There are exceptions (I'm looking at you VOX), but most 2 speaker setups are wired in parallel.
And here's something I can't answer, but I know it should be confirmed: If you're going to run two 8 ohm speakers in parallel, make sure the amp is seeing a 4 ohm load. I don't know if you can have the combo speaker plugged in, then use another amp jack for the 2nd cabinet. (My guess is no) Perhaps you've addressed this..I don't know, but it's important enough to make sure you've got it right.

When in doubt . . . ask the professional.
Hey Doc,
What do you recommend in this situation?
Thanks,

(My guess is no) Perhaps you've addressed this..I don't know, but it's important enough to make sure you've got it right. It requires the use of a”Y” cable. Do not use another amp Jack. I have done that with my former 2x10 Maz jr. and an 1x12 convertible cabinet. I ran it parallel, so I am no help as to the differences in sound. Our good friend Todd at Pro Cables and Sound can fix you up with either of your cable desires. Maybe buy both and see what you like best. Todd is PCNS here on the forum.

Thanks, yes I fully understand what is going on, and I've been through this several times over the years with a variety of amps. I'm just curious what others prefer, that's all. In parallel you have one speaker still going if the other dies in the middle of a song. Outside of that advantage, there is a different response/feel when choosing serial vs parallel. Then there's what the amp might prefer to see.
If any of you have been down this road, I'd enjoy your thoughts!

Just remember my views are slightly exaggerated to make a point. Parallel wiring : Both speakers fire together giving a more percussive response , more punch and fast attack . Series wiring : One speaker hits then the other as slight delay , like having a delay pedal at a very short timed delay. Your sound is thicker and sustain is increased. Z

Hey hey, thanks Doc. Nice explanation! Does the mkII have a preference, 4 vs 16?

Typically there's also less of a dampening factor with a lower impedance as well which will give a stronger/cleaner fundamental. Higher impedance, higher dampening, the harmonics will ring through which may give you a sense that the dirty sound is "dirtier."
All of this is extremely subtle and negligible for any sort of practical application though.
