Changing wiring for Technics SB-2866 speakers

I have these old technics SB-2866 speakers and was wondering if I can change the output of the speakers to be able to use XLR cables, as the current cable is thin, crap quality and feel like im not using the speakers to it's full advantage. Does anyone know if this is possible?

There is no reason why the speakers wont be able to take an xlr cable.

However, are you plugging your mixer directly into them?

Or are they active speakers/Passive with an amp?

Not sure if just using an XLR cable will drastically improve the speakers performance. Need a little more info on what you have and how you are hooking it up

Thanks,

im actually thinking of plugging my speakers into my soundcard. The output on the back of the speakers are designed for the thin copper wire, so how would I change it so it can plug in XLR cables?

Seems like you have passive speakers. They need an amplifier to power them, so you can't connect them directly to your sound card. You could change the wiring to XLR, but it would be totally useless as I don't think any amplifier outputs speaker signal to an XLR connector as it would be pointless.

Short version: No, it can't be done.

Can you take pics of the connections and tell us more about what gear you have and how it is connected as this all sounds a bit weird to me at least?

This is what i asked at the beginning. But all we've gotten so far is that they are now active.

End of the day, you can change connections to anything you want. As long as the signal has a path to flow down you should be fine.

Flimsy wires that you 'clip' into the back of those old school speakers, or a TRS/XLR wont really make a noticeable difference.. Both will get the signal to the speaker. Unless the cable you are using is absolutely knackered then going through the hassle of what i'm assuming will require you to solder your own connections or buy a host of adaptors will just be a pain in the ass.

But it is posible. You'll have to open up your speakers cabinet and find the + and - cables and then wire them to an XLR (female for example) then take the output of your soundcard (most likely TRS or RCA, maybe XLR which is why you're considering this). But if the output on your soundcard is RCA or TRS you'll have to have a cable with those connectors on the end of it with an adaptor on the other end to XLR to plug into your new speakers cabinet connection that you made.


That is all ridiculously confusing to read but i'm not going to bother editing it.

Any more questions, i recommend you give us a list of the equipment you're using and the connections you have in front of you already. And then tell us what you want to achieve. Lots of people on here should be able to help you out, i'll try again if i get more information from you.
