Wondering if solid silver would be the best internal wire for subwoofers and how it might change the sound for better or worse compared to solid copper (building a sealed 6.5 cu/ft with a CSS SDX15). Would it improve in say definition and speed but sacrificing the lowest frequencies.

The plan would be to either buy OCC bare 24 gauge for just over $2 or teflon coated for just under $5. Then I would twist enough runs together to make it 12 gauge equivalent. Otherwise if silver is a bad idea I would just go with one solid OCC 12 gauge copper run unless there are better ideas.

welcome 2 the diy forum. for your subwoofer driver i would use multi strand 12ga. perfect fot high current applications. silver is ok if its free [haha], homedepot has it 4 pennies per foot.
i use 4 1500watt amps and delivering current is the name of the game, not wasting money.
good luck with the build....

Silver would be a total waste.

With the length of wire used not only would any difference be inaudible, it would be unmeasurable. Copper is fine, and anything over 14ga massive overkill. BTW, there is no such thing as definition and speed where subwoofers are concerned. Those attributes are only found well above the subwoofer passband.

Well I guess the consensus is NO regarding silver. Thanks you all for saving me some cash on this.

Regarding Bill's comments on definition. I guess the aim of this sub build was to have the good attributes of my two other subs. One being a DIY 5 cu/ft sealed Tempest I built 7 years ago and a smaller factory built Rythmik Audio sub I also have.

The Rythmik has a hard time below 20hz and can't play super loud like my Tempest but it does have what I call definition or maybe the term would be pitch where when a kick drum hits it is more like a knock (both subs are low passed at 40hz).

Can anyone explain what contributes to this. Is it the QTS of the driver, the fact it is a servo sub, maybe the smaller size of the Ryhmik enclosure,or...?

Maybe if you look at just the frequency domain, but a high system Q will have overhang/less definition at bass frequencies.

Do an RTA and you'll see a lot coming out of that sub well above 40 Hz. A high amount of above bandwidth harmonic output is a characteristic of direct radiating subs.
