As my speakers have 99db or more efficiency I definitely dont need thick wires. I am thinking 2x18awg and 2x20awg at the max or even 4x20awg. I know not typical orthodoxy but Acoustic Revive and Morrow (and DNM) seem on similar path..
Combined Wire Gauge Calculator
4x20awg?
Is that 4x20awg for the Pos and 4X20awg for the neg? Or 2x20awg for the pos and 2x20awg for neg?
4x20awg _ effective gauge 14awg
2x20awg = effective gauge 17awg (slightly larger than 18awg) Too small, IMO...
