[QUOTE="Art Welter, post: 24518, member: 52"] Re: How many watts is my sub getting Do not try this experiment with the bass player's 300 watt SVT tube amplifier unless you have lots of money set aside for repairs :^). Also, there are many loudspeakers that will not survive 50 volts of 60 Hz sine wave for more than a few seconds, as I have found out by mistake :^(. However, a B&C18SW125-4 can survive a 110 volt 60 Hz sine wave for over three seconds 3 times in a row, it takes about 3 seconds for a Crest CC2800 in bridged mono to kick it's front panel breaker, as I found out in a more recent mistake when I thought I was turning down the LF level while on the HF page... Previously, I was suprised to hear the same speaker not complain with 120 V, however it turns out the impedance at the frequency I was testing was around 18 ohms, so the speaker and amp were "only" using 800 watts, which did not trip the amp's breaker, but did rattle various stuff off the shelfs in the shop.
