I'm assuming that the speakers are of the same impedance (like 8 ohms or 4 ohms whatever the original was).
Yes it is an 8ohm just like the other.
I can see from the pics that you've used fairly thich solid wire to connect to the speaker. Just how hot was the soldering iron and how long did you hold it on the speaker terminals when soldering? It's one of those jobs that needs to be done as quickly as possible. It looks like you might have heated up the voice coil to point where the adhesive has let go. You've also got a lot of bare wire exposed on those speaker leads.
not sure on the temp as it does not have a selective temp. The speaker came with soldering already on the leads it held it on them long enough so the wire end could attach itself and re solidify, which was very quickly. So I'd have to re heat it, maybe that when its happening with the thicker wire.
I'm
Pare only as much insulation as you need to connect it. First tin both the speaker terminals and the bared copper wire ends with a little solder. Then place the two tinned surfaces together and apply heat long enough to get the solder to flow. Remember that thick wires and different metals will act more as a heatsink than others and need more heat. It really pays to practice on something a bit to get used to how hot the iron needs to be for the components and the type of solder and how long you need to apply the heat for. If you can adjust the temperature of your iron even better. It needs to be just hot enough to melt the solder quickly. If you ever decide to try soldering transistors or ICs remember heat can be a killer.
So try the extra speaker if you have one left following those tips and see if it helps. Maybe practice on a bit of the perfboard I saw in the photo and try to solder some wires to it quickly.
ps. I can see from the photos that you've applied a lot of heat when soldering wires to the circuit board. Be really careful as you can lift the copper pads (connection areas) off the board with too much heat.
Yea luckily I have one more of those speakers left that I ordered I can try, But I'm told now RadioShack sells them (whew) so I don't have to order anymore. I didn't tin the end of the thicker wire so that also maybe why.
the heat marks could be from having to reattach the original wires back to those spots several times because of them breaking during when I was setting up. I thought of maybe just reordering the board, since I don't think I have any of the original type of wire and nowhere near me sells it. I could order a spoole of it, but I honestly don't need that much of it and I figure I can get a clean board also. I might play with what I have first, since the electronics is basically all I have left.
thx for the help.
