Solder only and Push on Speakers in a 4x12...

Marko1986 · 03-19-2010, 05:47 PM

Hey guys,
So I just got some Heritage G12H30 and want to drop them in my cabinet. I have a Marshall 1960BV cab with an impedance switch. The G12H are solder only while the V30s are push on. First question is, is it fine to just solder the speaker wire straight to the terminal of a push on speaker (I don't see any problem there, just want to be safe)? And secondly, since I have an impedance switch, is it ok to solder 2 separate wires to the single positive terminal of my G12H30 (one wire connected to the other G12H's positive and the other wire connected to the terminal in the impedance switch)? Hope that is clear, thanks in advance for any help!

Sure - soldering one or two wires directly to a push-on terminal is fine, although a bit tricky. Be sure to get as much "wire-to-terminal" contact as possible, and get a good solder connections (nice and shiney) without overheating the terminal (which could cause the lead wire to drop out or stiffen).

Ok cool I figured as much with the push on. Now my last and only question is; on a solder only terminal. like the picture I attached, how should I attach 2 separate wires? (one wire from + to + of the other G12H and the other wire to the Independence switch). Is it ok if the 2 wire ends are touching each other? This is the first time I have changed my speakers so any help would be greatly appreciated.

Just thought of something, instead of soldering two separate wires to one terminal, would I be able to just run 1 wire, strip the section that needs to be in contact with the terminal, solder it and run the same wire to the + or - terminal on the switch? I drew a sketch real quick to explain what im thinking and attached it. That would be just one continuous wire and I know I'd have to do the same thing with the negative terminal I just didn't draw it. But would this be fine, I cant see there being a difference between this or soldering 2 wires that are gonna be on the same terminal. Again, any help would be greatly appreciated guys!

When wiring speakers, at some point you're going to have two wires on the same terminal. One wire will be the feed which the speaker it's connected to draws power through, while the other will be the feed to the next speaker down the chain.

You seem to have the right idea. Each pair of speakers should be wired in parallel with each other (i.e. the (+) of speaker 1 in pair A would wire up to the (+) of speaker 2 in pair A while the (-) of speaker 1 in pair A would wire up to the (-) of speaker 2 in pair A. Same applies for the B pair. Then a second set of wires would go from speaker 1 in pair a to the impedance switch. Same for pair B.

Thanks so much for the reply! Yes that makes perfect sense to me and that is exactly how I wired up my cabinet. Now my final question is, since you have to wire 2 separate wires to one terminal when working with an Impedance switch and solder only terminals, isn't that essentially the same as doing it with 1 wire? As long as you remove the insulation of the wire halfway through, solder it to the terminal of speaker 1 pair a, running 1 wire end to the impedance switch and the other end to the same charge terminal of speaker 2 pair a? Just like the diagram I posted above in my third post, the attachment titles 1 wire. If you could answer this last question I will be all set man, thanks for all your help!

Yes it's the same. Splicing two wires on the same terminal effectively makes the two wires into one.

You are the F'in man! Thanks again dude.

Using one wire and just stripping a little insulation in the middle to solder it to the first speaker is a little unusual, but it will work fine.

I put a G12H Heritage in my 4x12 also, I soldered two wires to the speaker terminal. I used heavier gauge wire too so it was tough to get both wires on that little tiny terminal. It made me wonder why the solder only terminals were so small...smaller than the push on type. And they don't have through holes so you can feed the wire through the hole and get a good mechanical connection like the push on type. Seems silly to me.

I think the OP is asking about soldering technique too: when you have to have two wires go to one terminal, what's the best technique? Personally I try and avoid soldering both individually at the same spot because I'm afraid of one wire losing a good tight bond as I'm soldering the second one. Instead, I twist the two wires together tight, solder that junction, then solder that to the terminal. I do not know if this is good technique or not though!

Comments?
