In Reply to: What's the smallest wire AWG that you feel confident using for speakers? posted by Quiet Earth on April 1, 2007 at 09:11:36:
Hi.It various from amps & the length of speaker cable used.
AWG#22 handles max 2.5A (60C UL rating), & 3A (National board of Fire Underwriters rating).
So, for your 9W/8R amp, it draws 1.06A at max load. So theoretically, it works with #22 wire with a FLAT 8R speaker load.
But the impedance of a loudspeakr swings up & down like a roller-coaster per the music frequencies. It never stays at its rated 8R impedance. It can be up to 35R peaks or down to 4R at valley deeps.
So much larger size speaker wire is always recommended to make way for instantaneous large current draws at the impedannce deeps.
I won't not take speaker wires less than min. #16 gauge.
FYI, I am using two pairs of #12 oxygen free high conductivity copper cables for my outboard bi-wiring speaker systems.
