While learning about crossover components, I came across a site that recommended matching the resistor wattage ratings to the wattage of the driver in use. Here's the page: http://www.lalena.com/audio/electronics/rcl/ I noticed that on some DIY sites that explain the crossover and list the exact parts, they use resistors from Parts Express with a wattage rating considerably lower than the driver they're in line with. Is this alright to do? I assume so since highly regarded DIYers do so, plus there's a scarcity of high-wattage resistors on Parts Express. Could using a resistor rated too low cause damage? For example, a 10W resistor would seem to limit SPLs somewhat.
