Monoprice Speaker Wire, CL2 Rated, 2-Conductor, 12AWG, 99.9% Oxygen-Free Pure Bare Copper, 100 Feet, Black
The heavier gauge for long runs and 4 ohm speakers. Pure copper and in-wall rated, from the same line as the 14 AWG spool.

- 12 AWG
- 99.9% OFC copper
- CL2 in-wall rated
- 100 ft
Twelve gauge keeps loss under 5 percent out to about 125 ft at 8 ohm, or about 60 ft at 4 ohm, so it covers long front runs and low-impedance towers. It is the same pure copper CL2 line as the 14 AWG spool, just heavier.
Watch out: Twelve gauge is stiff and thick; check that your speaker terminals and wall plates accept it.
Pros
- Pure OFC copper
- CL2 in-wall rated
