I got my speakers in, but I'm not exactly sure how to wire them up. Are the cabs wired the same as a Marshall. Both sides parrallel with 16ohm speakers? Meaning run one set of + - to the top left speaker from the jack plate, then run the other set of +- from the jack plate to the top right speaker, then connect in parrallel the bottom left speaker to the top left speaker and the bottom right speaker to the top right speaker in parrallel? Or is it wired differently?

This may sound crazy, but on the celestion speaker web page, they have a wiring diagram for speakers. I believe this should be a univ. diagram. I hope this helps.

Okay. I looked at the diagrams and the bottom right one looks like the wiring on a Marshall cab which I am assuming is the same wiring on the Splawn 8 ohm Stereo which is both sides paralleled separately.

Yep............that is correct. Just verified it IS wired just like a Marshall cab.

What I do when done wiring...is take an old mostly dead 9V battery tape/solder wires to
the +/- wire of the battery. Then I briefly touch positive/batt to positive/spkr jack
and neg/neg etc. ALL speaker cones should excur outwards if they are wired in phase.
If any one cone moves inward, reverse this speakers +/- terminals.
You'd be surprised how many speakers are either mismarked or miswired
causing thin bass response, impedance mismatches etc. ACTUALLY...
It's not that common but I always check anyway.
OH and BTW...a typical 4x12 cabinet with 16ohm spkrs are
all wired the same with a combo of series/parallel wiring
yielding a 4 ohm load. Pretty standard stuff.

Does anyone know if the black wire in a Splawn cab is positive or is the red wire positive? I may have a slight phasing problem.

Usually the red wire is positive. But realize, that's from the perspective of coming off the jack. As the wiring chain progresses this can change depending on how the speakers are wired.

Okay after some tinkering and testing the wires, phase with a battery etc I found the problem. One of the short wires was no good. It had a break in the wire in the housing thus the phasing and tone issues. I thought the jack plate may have a solder issue or maybe a wire crossed. Fixed the wiring issue. I installed the G12 K100s in it and loved it, but it has a ton of bass. It didn't really compliment the Avatar with the Texas heat/ Governor Xpattern (unbelievable crunch and thunderous). So I put the two heats and two govs I had sitting in their boxes into the Splawn. Dude.
I think I have found the ultimate combo for the Nitro. FINALLY! Both cabs running with the Heat/Gov combo slams period.

how do you check the phase with a battery? i've heard of this but would like to learn more.

The idea is you connect the terminals of the battery to the speaker and then watch to see if any exude in a direction that differs from the rest. They should all move one direction. That's the theory anyway, been hearing about this for many years and never bothered to worry about it. Assuming the person who wired your cab knew what they were doing then the only way you'd have a phase problem is if a speaker was wired incorrectly (REALLY rare).

Yeah or you can plug a power cord into the jack plate after wiring up the speakers and then touch the positive on the battery to the power cord tip and the negative to the shaft. All speakers should fire forward. If they all don't fire forward then you will know where your out of phase speaker or speakers are. This is how I found the issue with the speaker wire was. All speakers but the bottom left one fired forward. It fired backwards. It was wired correctly, but had a bad wire. It is fixed and I am in a tonal bliss heh heh.

what kind of power cord are you referring to?

Actually, an kind of two-conductor cord will do for the purpose of this test. Even if one is a shield, such as the case with an instrument cable.

I meant speaker cord or cable. Not power cord oooops.
