[Bob Snelgrove]

Which is positive if it matters?

Yellow +

Yellow +

Thanks, Dave

Should have written it down

Hopefully going to an 8 ohm pF 350 won't rob too much power!

Curiosity question :

With a single speaker, does polarity really matter? I've heard that it really only matters when running more than one speaker.

That is correct. Doesn't matter for single driver but it also would matter when running multiple combo amplifiers for the same reason. You want the speaker cones to move in unison regardless of how you push them.

Thanks Bob.

Well:
Negative/Negative &
Positive/Positive
Makes the speaker move Outward.

Negative/Positive &
Positive/Negative
Makes the speaker move Inward

The best sound for speaker is:
OUTWARD

So you can hook wires to speaker; then get a 9volt and put positive on positive contact on speaker and negative to negative and you'll see the speaker either pulse forward or backwards and that will tell you your answer of what wire is what.

To add to what Bob Sykes said..........

You could have two amps, inputs connected with a Y cable or whatever, the inputs being in phase.
The speakers could be hooked up correctly as well.

However, if the amps are different, there could be a phase shift in the circuitry that would ultimately result in the final sound coming out of the speakers being out of phase.

If you ever hook up two amps and the sound seems thin, you can simply reverse the speaker leads on one of the amps.
If it sounds better, then that is your fix.

Years ago, a bassplayer friend was working with a lead singer who bought a Dual Showman to play rhythm guitar through. He was a great singer, and front man, but a lousey rhythm player, and he was way too loud! Before the gig, my friend went to the club, and wired the speakers in the cabinet out of phase, on stage the guy heard his amp well, but the audience heard the two speakers cancel their sound.
He said the rest of their dates, everybody was happy!

I like to hook 'em w/positive polarity just to maintain. In the event one has the occasion to use 2 in a single situation, then you don't have to worry about phase if you wire them like that initially.

Then you got JBLs and JBL clones that use reverse polarity so you need to pay attention there.

Whether excursion is first forward or backwards in a single speaker is something I've not paid attention to. As someone else stated above, that might be a consideration in some cases.

The Mid Eighties Jay Dee Maness sound was from having one speaker out of fase or one amp with the +&- reversed if you will. Of course having the SPX90 and Yamaha 1005 helped.
The 8 ohm PF350 will need that you crank up the volume quite a bit on a NV112.
Good luck.

That happened to me. I was using a Nashville 400 and Peavey Studio Pro 50 together. I had put a JBL in the Studio Pro and was wired backwards from the NV400. Swapping the wires helped.

Then you got JBLs and JBL clones that use reverse polarity so you need to pay attention there.

That was why my Studio Pro was wired "backwards".

For speaker wires that aren't black and red, like the terminal designations are on most speakers I have ever seen, I take black and red Sharpie markers and color the wires about an inch or two near the end of the wire where they connect to the speaker.
