Calculator cluster
Amplification & power
Amp matching, speaker wire gauge, AVR heat, conditioners and Ohm’s-law rack load.
Amplification & power
Amplifier Power Match (SPL) Calculator
From speaker sensitivity, distance and target SPL, get required watts and whether a receiver can supply them with headroom.
Amplification & power
AV Receiver Heat Dissipation Calculator
Estimate heat in watts and BTU/h from idle draw, load and efficiency, then a starting ventilation gap.
Amplification & power
Ohm’s Law AV Rack Load Calculator
Convert rack watts and wall voltage into amps and check the 80% continuous-load breaker rule.
Amplification & power
Power Conditioner Sizing (VA/Watts) Calculator
Sum display, AVR, sources and extras, then add 25% headroom for a conditioner or UPS VA rating.
Amplification & power
Speaker Wire Gauge (AWG) Distance Calculator
Pick a minimum AWG so round-trip copper stays under 5% of the speaker impedance on your cable run.
