Just to be sure........

[bigdaddyweed]

Hey all,
I have a question that may seem too simple, but I'd like to be sure. I have a Maverick 2x12, and want to know how the speakers are wired. I got this used, and it has 16 ohm Celestion G12H30's in it.

So, are they series, or are they parallel?

Also, I would be interested in trading this great combo, minus speakers, for a Maverick head, preferably the long one. As soon as I have enough posts, I will put this request in the classified section.

Also, what is it with these Mavericks? I have other amps, including a Dr. Z Maz 18, and they just sit at home while this one goes out and rocks.

Later...............weedman

Th easiest way to tell would be to look at how they are wired. If there is one wire going from the plug to each speaker with a jumper between speakers, then it's wired in parallel, which is most likely the case. 2x16 in parallel = 8 ohms.

If there's two wires going from the plug to one speaker, and two jumpers between speakers, then it's series. 2x8 in series = 16 ohms.

This description isn't sounding quite right; in fact reversed for series and parallel connections (however the math is right for calculating the impedance). I'll try to draw out the correct version below; we'll see how it represents when I post it:

Parallel is as follows:
Speaker plug contact ---------------------------------------
| |
| |
3 3
3 (speaker 1) 3 (speaker 2)
3 3
| |
| |
Other plug contact ------------------------------------------

(By the way, there is no significance to the "3" except that it makes a handy way to draw an inductor, which is what a speaker voice coil is.)

Series is as follows:
Speaker plug contact --------------------
|
|
3
3 (speaker one)
3
|
|
3
3 (speaker two)
3
|
|
Other speaker plug contact -------------

Hope that helps.

Well, the post stripped the leading spaces...if you imagine the vertical lines on my drawings being much further to the right, you'll get the idea. In general:

For parallel, one side of the speaker cable is connected to the same terminal on BOTH speakers. The other side of the speaker cable is connected to the OTHER terminal of BOTH speakers.

For series, one side of the speaker cable is connected to one terminal of one speaker. The other terminal of THAT speaker has a jumper over to the first terminal of the second speaker, and the OTHER terminal of the second speaker is connected to the second lead of the speaker cable.

My mistake...I'm all doped up on Nyquil from the damned flu....

Yeah xarkon, you're right. I have my stuff all turned around. Don't listen to my first post.

There's a reason they say not to operate heavy machinery and such when taking Nyquil.... :lol:

No problem...I figured that you might have switched the names around since the impedance calcs were right. The flu this year - well, don't wish that on anybody, took me weeks to get rid of it.

Thanks guys, I think I have it under control.
