Help me build speaker cables please!


Howdy!
I’m looking for input on some home brewed speaker cables. I’m currently using cables I made from braiding 8 lengths of CAT 5 plenum cable together. They’re terminated in silver plated BFA bananas and set up as a biwire configuration at the speaker end. I love their sound, but think I’m ready to try something made from higher grade metal. I’ve been doing a lot with silver in my system and have loved the change in sound almost every time I’ve gone from Cu to Ag. The only place I like Cu better is in the PCs for my amps. That said, I’m leaning heavily towards making a set of solid silver speaker cables, using .999 silver wire from Rio grande. I’ll insulated them with teflon spaghetti tubing and possibly terminate them with silver plated BFAs.

Where I’d love some input is here: do I do one run of 10awg, or biwire 12awg to the woofers, 14awg to the tweeters and mids? I’m using a dared tube preamp and monoblock Ghent audio class D amps (500w into 4 ohm) which drive floor standing RBH 1266 SE/R speakers. They are 4 ohm and have side firing 12" speakers. They like a lot of juice and sound their best when given what they want, hence my desire for large diameter cables.

Cost wise, it’s only $50 more expensive to biwire. I liked the change in sound when I first biwired, but I also went from blue jeans twisted pair 12 awg to my braided CAT 5, which has a combined 9 awg. So I’m not sure if it was the biwiring or all the other differences that improved the sound.

Also, any other ideas for superb sounding DIY SCs are welcome.

Danke!

@toddverrone  - just finished te second cable.

Second one was easier, but I now have blisters on blisters - and that was using gloves.:-(

Will keep you posted as to the sound

Cheers
@toddverrone not being able to wait for the bananas to arrive, I crimped some bananas from an old pair of speaker cables onto the Helix.

Here are my findings...

For starters - 16 gauge appears to be perfectly adequate for bass reproduction
- the bass does change and I found I had to play several tracks to appreciate just what changes had taken place.
- the bass is now very detailed and very controlled, so on some tracks it appears the bass has diminished, but that is due to a less bloated bass
- on my bass test track - a song called Undring, by Sigmund Groven and Iver Klieve the bass on the pipe organ was actually fuller, more vibrant and very well controlled - important for pipe organ reproduction, whilst the hamonica was very detailed and stood out more than usual
- Albums by Stevie Wonder and Peter Gabriel also confirmed the bass is in fact fuller and more dynamic

Clarity is amazing.

The dynamics are exceptionally fast.

Image width did not change a great deal, but the depth and height is much improved.

I thought I had very good speaker cables - I do now :-)

This has been a total surprise - I tried this because you had decided to try the helix, which inspired me to see what helix could do for speaker cables on my system

So I thank you for that :-)

Since the conductors I selected were very good, but not what I would call exceptional, I thought I would be lucky to match the cables I was using - boy was I wrong.

Can better conductors improve things even further? I might get around to testing that one day :-)

Seems the helix design works very well for speaker cables.

The new bananas should also improve thing a little

I’m listening to some orchestral tracks while I type this and the sound is very natural sounding with improvements in the venue acoustics being very noticeable.

What I am wondering is - will the 12 gauge bring out the same level of details and expand the depth of the image as my 16 gauge has?

BTW - I normally wait for the burn-in process to complete before posting results, but these improvements were so startling I thought I’d give you a taste of what should be coming to your system.

I really hope you get to experience the same level of improvement.

FYI - all my cables are now of the Helix design.

Keep me posted and let me know what your findings are.

Cheers
@tsugury that's funny. That was one of the first articles I read on DIY speaker cables when I first started making them about a year ago... Never tried them though. I doubt that same extension cord is still available. I like fancier designs anyway. Thanks for the share though. Have you tried them?

@williewonka excellent! I'm excited to experiment with mine. I'm interested to hear what gauge signal I like best. I have a feeling it's the bigger neutral that makes the most difference and that having a large (10-12awg) signal conductor will also sound good, as long as the neutral is double the signal. But we'll see! Or hear..
toddverrone, Yes I needed a longer run,20' due to change in rooms. I think they sound excellent considering the price.Much better than zip cord that's for sure. Although I am partial to JPS in my system.YMMV, TG
