I am sure there will be quite a few people on here with the 705s or similar. I have the S3 version and am happy with the sound in my room, but as always one wonders if a small tweak might improve things!
So, is it worth replacing the connector that comes with the speaker? It looks pretty chunky. If so what should I replace it with and how should I wire it up. I have done a search and found a cross wiring recommendation on the forum so could try this. There are also other generic threads some saying it is worth doing but nothing this specific.
I am not looking at spending hundreds but if Ā£50 would be a worthwhile tweak then why not?
Happy to buy new or used or even make my own, though I donāt have a crimping tool or any soldering skills.
Personally speaking Iād use the original links and diagonal wire them.
The speakers are designed to use whatās provided and adding more connections and plugs isnāt going to improve things.
If using passive keep the links in place and put positive to the uppermost frequency driver and the negative to the lowest.
This worked best for me previously and was recommended by a speaker designer.

Explanation.
The reason for this is that you always have the same impedance between the amplifier output and any drive unit in the system (the length of speaker cable plus one full link plate). It is also important that the negative wire goes to the bass negative as it gives the clearest path for the back e.m.f. from the bass driver to be sunk back through the amplifier, reducing its influence on the other drivers in the speaker.
The diagonal wiring arrangement as proposd by @Skeptikal was recoomended to me also by someone from The Chord Company. I found that replacing the supplied (and fitted) metal link plates on my Klipsch Forte III speakers with Chord Signature X cable jumpers made a very worthwhile improvement. Note that you should use the best quality jumper cables that you can afford - they donāt have to match the main speaker cables. My main cables are Chord Epic X.
Why not follow the example of the legendary Jimmy Hughes and make your own jumpers from 10mm cooker cable. At about Ā£5 per metre itās got to be worth a go.
Well, I hope weāre all well past the era of thinking that mains cable makes satisfactory speaker cable! It may have cut the mustard 40 odd (very odd!!) years ago but like some other ideas of dear old Jimmy, such as removing the internal wadding from your speakers to āimproveā their performance, itās best consigned to the museum of curios from the dim and distant past.
Iāve got the whole blurb but thatās the main reason Phil Budd at Linn explained it all.
