Have a question to see if anyone on here can help. I have a pair of Swan Diva 6.1 speakers that I’ve had for about 8-10 years. After some years of abuse by my kids, a couple of the HiVi 8” woofers have dings and some of the rubber surrounding is coming loose on speaker. I thought it would be an easy replacement….. Meaning, purchase 2 new M8N Hivi’s from parts-express and away I go, but come to find out, my diva 6.1 speaker has M8N-16’s in them. This 16ohm speaker is non-existent for purchase from what I can tell. So that leads me to this question. There are 2 M8N-16’s in my diva 6.1 that are wired in parallel back to the crossover, so that is an 8ohm? Hivi only makes the M8N (from what I can see) in an 8ohm, so do I need to have my crossover redesigned to make these new 8ohm drivers work? I’m including a picture of the existing crossover and the M8N-16 speaker. What do I need to do to use new M8N 8ohm drivers? Sorry for the crazy post, just hoping to put some new life back into a pair of my older speakers.

If OP wants to experiment with new woofers he have to change the woofers (8 ohms) coil to a paralleled new woofers (4 ohms) crossover coil.
6 db Crossover Table
tmkaiser,
If you are experimenting/testing you go to the table where it says 8 ohms let's say a 1 mH (your component value/measure it) for the sake of an example, and change it with 0.51 mH inductor.
Real numbers for inductor values are not possible unless you know hwo to design and simulate speaker systems.

I was actually watching that auction and was planning on buying them, but didn't know how rare they were and that there was a difference between M8N at parts-express and those 16ohm models..... It was only when I took the woofer out of the speaker box, when I found it was pretty rare. I'll continue to watch and see if any come up.
As for the glue, I guess I could try that. Any suggestions on what glue to use?
So I'm getting the understanding that I'm not going to be able to rebuild the crossover to work with the M8N. unless I have someone on here that knows how to analyze both crossovers in the speakers and tell me if that will work.
I also tried to reach out to Hivi, but not getting any responses.
Oh yes, you should!
Some say vynilic glue, I prefer rubber cement( for foam or rubber surrounds)
I suggest to try to lift also the attached surround, 'cos it will detach later...
Inductor's suggestion about halving the inductor value/ doubling the cap value will get you very close for the 80hm M8. If you can get the existing values off any parts in the woofer xover that will get you started on the right foot.
At least now we know what those 16 ohm woofers are for. There was some discussion about them at PETT forum when the auction was on but no one knew if they were a misprint or what.

It would be interesting to play with those woofers as singles.
In that case, the inductance needed for the lowpass filter would be double than for 8Ω.
<some drivers from the double driver configurations of the '70s such Pioneer, Kenwood, Sansui are 16 Ω and they come for cheap>
