Speaker Cables

IMO whatever you do, recommend NOT using the home depot brown spool wire some people talk about, it's garbage for internal speaker wiring too. Super grainy result from it in my setups.  Not helping you with your color-coded black/red wire desire, I've been using the White Supra for over a decade in my builds (same as Omega does today, reportedly), yes you can go with thinner gauge with the tweeter. Cardas and Analysis Plus use to offer some nice internal wire too, yet I've only stuck with the Supra knowing its signature. As others have said, its not as bright or detailed and its a preference thing I guess.   As for speaker terminal binding posts, it varies for me using the generic ones Madisound sells for lower grade builds and Cardas binding posts for the nicer builds works nicely. Try the junk ones and the good ones, solder them on with silver solder and you may hear a difference.  Your experiences may vary. Good Luck.

For your speaker wiring project look at this:

Especially check the current rating on it. It indicates 124 Amps for 8 AWG wire.

The amperage rating of this wire is a testament to its low resistance.

As for inductance & capacitance, for the very short runs of cable you are likely to have inside a speaker cabinet, they will not be significant.

Its max working temperature of 390 F is also worth considering since it will not be a fire starter should something go wrong inside your enclosure.

You will be hard pressed to find something along the same lines for that quoted price.

I have no experience in rewiring a speaker and would follow deconny's advice. Both my Tonian Labs TL-D1 and Clearwave Duet 6 speakers were internally wired with Supra and they sounded great.

It's just with speaker cables that I eventually passed on the Supras with.

All the best,

Surely Duelund or Neotech.  Partsconnexion has Duelund hookup wire, Take Five Audio has Neotech.

@jjss49 - I experienced problem using a heavy gauge (i.e. thicker than 18 gauge) solid Hookup wire for my speakers.

I do realize that solid is better than stranded wire, but if your crossover is mounted on PCB like mine, there is the possibility that the copper trace on the PCB could separate from the board and break. I suffered this issue many years ago. I changed to stranded

There are some very good stranded wires out there e.g. my favorite, Neotech UP-OCC copper or UP-OC silver

If the Crossover is point to point wiring then it might not be an issue
