Confused how to wire parallel two speakers in 3 way?

[elijahscott]

I have this diagram with an 8mh inductor on the positive line but how do you wire them out into the rest of the bunch?
Is it number 1 or 2? I assume it’s two with both positives connecting out. Not my first drawing?
This is a 3 way and there’s only a 8mh inductor on the two woofers and wired in parallel.

Judged from the mid section (8Ω nominal?) the woofers should most likely be in parallel. Are they 8Ω nominal too? Or even 16?

Try the idea of connecting the drivers to each other first. This way, the inductor is in line with the pair.

Yes, they are being wired in parallel. They 8ohm nominal

I have the inductor on one side of the cabinet so I’m not sure I understand. One end comes.
Are you saying wire them together first (+ to + & - to -).
Then wire one speaker out and connect to the inductor and then out to the rest?
I don’t know if that would make a difference then having the inductor one end to one positive on the closest speaker then another line out from the second speaker and connect them all. Would save on speaker cable that I don’t have enough of if I re-wire it the way you said?

This should clear things.

 

[AllenB]

Yes, that will do it. This is the same.

Don't worry too much about those things, just keep the parts in the right order and make them neat according to the ways of wiring.

That helps great. I’ll rewire it so the inductor positive heads outwards

So now may we have your votes for the best scheme please? 😉

Just in case: if the bass plays too loud, there is a possibility the designer meant the drivers to be connected in series with each other. I ruled this one out swiftly, but we cannot be 100% certain. But first try the plans above.

I wondered too, because 8mH/4ohms is 80Hz.

Yep, but depending on baffle size, response trend etc the acoustic crossover might be an octave higher.

Is it? He said the crossover for the woofers is 200hz. The midrange takes over from there.

 

[Lojzek]

What woofers are these, any datasheet?

 

[elijahscott]

Peerless by Tymphany HDS-P830990 - 6.5" Woofer
They are two of those

I wondered too, because 8mH/4ohms is 80Hz.

What inductor would be the same with an 8ohm driver? 4mh? Or does it go the opposite way? So 15-16mh?

 

[AllenB]

Yes, 16mH (acoustic response may cause variations).
