3 sizes – $5/m, $7/m for 2 core, $12/mtr for 4 core to bi-wire, new and high quality copper, positive (red) identified.
Even the $5/m size is high quality, ideal for those terminals on amps & speakers that won’t accommodate thick cables or banana plugs.
If you want to bi-wire your high quality speakers, the 4 core reduces the spaghetti effect of multi-cables.
All are banana plug compatible. Make sure your cables are the same length to each speaker, even if they are not equi-distant.
