Good quality copper cables, nice and flexible

Lets not go there when it comes to discussion of quality of sound reproduction etc - bottom-line, its decent gauge copper than easily conducts high current; I have a separates-system power amp pushing high RMS per channel when required, and these do a great job right up to very loud SPLs

Purchased three 6 foot banana plug pre-made speaker wires, the Micca Pure Copper, the Mediabridge 12AWG Ultra https://www.amazon.com/gp/product/B01CYGMD4I/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1 , and the Cable Matters Heavy Duty 12AWG https://www.amazon.com/gp/product/B00NB4TB66/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
