Wire to repair Bose 901 speakers

[JohnMichael]

get your soldering iron out.

make it hot, do it quick.

16gauge OFC copper will be miles ahead of the original cable too...

His series of 901's have 9 individual enclosures inside the speaker. I can not remember what they called this technology. Since the wire has to be thin enough to feed from internal chamber to another some 16 guage cables will be too thick.

Good day!

I have been away for a long time and have not finnished the rebuild project yet. I was concidering replacing the stock wire with a larger gauge better quality wire. I was thinking about using a pencill type solering iron to melt the holes between chambers bigger then once the wires where installed, I was going to seal them with some undetermand sealing compound to make them air tight and to prevent the wire from vibrating against the plastic.
I was also going to make them a little bit longer to make installing the drivers easyer but not too long so the wires do not touch inside and vibrate making noise. I was going to solder the wires to the drives but I would use a small set of needle nose vise grips and lightly clamp them to the bottom of the pin. This will act as a heat sink and help prevent the plastic basket from melting. Solder the wires at the end of the pins as far away from the basket as possible and do it quikly but make shure you do not get a cold solder conection as this would defeat the purppous of soldering all together.

B,

FWIW I am fairly certain that the wire is aluminum. Replacing it with different wire will change the sound...you may like the change but keep in mind that the speaker was voiced with that wire in place. IME aluminum can sound tizzy or somewhat bright. So you may lose some high end that might be needed.

In addition, thicker gauge might not be an improvement. Especially if it is stranded.

And using a different wire like copper will almost certainly mean a mismatch of metals which may not be good sonically. Jon Risch has some papers about dissimilar metals.

I just got home and looked at the stock wires in the speakers and they are tinned copper and the pins on the driver pins are steel so I do not think the mismatched metals was a problem back then and shouldn't be now.

Ok. I should have looked closer. YOu have the 3 series. I was talking about the latest. Sorry
