Korean amplifiers achieve their total wattage output with a higher amperage output, hence why their internals are extremely beefy and thus the amps more costly. Conversely to that, Brazilian amplifiers significantly step-up output voltage to hit their wattage numbers, less current throughput reduces the need for beefy (heavy gauge and extremely stout) internals and thus reducing costs for the same total wattage. Here is where my question begins, 7kW =/= 7kW, what I mean by this, is a 7kW total output can be achieved with 200Volts and 35Amperes or 46Volts and 150Amperes.. Electromagnetic coils (The coils in the woofer) have a direct relation to magnetic flux saturation and amperage.. Meaning, more amperage, more magnetic flux lines, meaning a stronger magnetic field, thus leading to a more powerful excursion.. So, wouldn't Brazilian amplifiers technically fall short even at the same "wattage" level?
