I dont know if this was a sales ploy from the rep but back in the day we sold Fultron audio (this was before they turned into Memphis audio) and the sales rep said that they just built a woofer and was in a marketing meeting for it. The rep said that they plugged it into a wall outlet to demo the capabilities of it. They left it plugged in for the majority of the meeting and never burned out. I have not ever tried it but for a woofer to handle 115v @60hz with whatever amperage the circuit could handle, at the time impressed me but I didn't know much about all these high wattage woofers at the time.
