Series? Or parallel?

[JackBootedThug]

For two 8 ohm speakers. Any reason to pick one over the other? Just bi-curious…

Depends on what you want your final ohm-age to be?

8
Edit-I guess it doesn’t matter but probably 8 is best for my setup….

8

You can't get 8 out of 2 8 ohm speakers. You can only get 4 or 16.

I thought 8+8=16/2=8…. Am I retarded? This is why I ask. I don’t know…

Yup just looked it up….

In series, you add the numbers together.
Speaker 1 plus speaker 2 equals your impedance.
8+8=16

In parallel, it's a little more complicated. The formula is (X×X)÷(X+X). We can simplify it when the speakers are the same. X²÷2X.
(8×8)=8²=64
(8+8)=2(8)=16
64÷16=4

If you use the correct formula, it helps with mismatched speakers too.
In series, 8+4=12
In Parallel, (8×4)÷(8+4)=2.66 because 32÷12=2 1/3

That only works with 4 speakers, like in a 412 cab.

Fast answer on identical impedances is that two identical items in parallel have exactly half the impedance of each one individually. No math (well, halving) necessary.

I like asking here before doing a three second google search… because I value the homies opinions more than google!!!!

 

[rstites]

That's actually a good idea. Definitely skip the AI search as I stumble into a lot of outright wrong answers with that. At least, go to wikipedia and peruse their answers. Those are generally correct.

Here's a good site to use for calculating total speaker impedance. It lets you select series, parallel, series-parallel, or parallel-series. It can even give you how much power is going to each speaker. Just select the appropriate speaker wiring and plug in your numbers.

If running a solid state amp I would do parallel for 4 ohms. Tube amp I do series for 16. That way I can run two cabs for 8 ohms when needed.

I've had Google send me right back to Rig-Talk when I ask questions, so you're not wrong. We are the sorce of the AI answers anyways.

Ai keeps saying that the angle of the dangle is perpendicular to the trickle of the dickle…wtf
