UK and US watts...

Discussion in 'Amps and Cabs [BG]' started by The_Bass, Jan 5, 2001.

  1. it´s 3:10 am. here and I´m really tired so I´m sorry if I post some crap...

    but is there a difference (or was) in UK and US watts?

    it says on two 18" speakers I have 50 w. US, 110w. UK... :confused:

  2. Watts are the same everywhere. 1 joule of energy per second is 1 Watt. I can't explain what you have on your speaker, except maybe the US pretty much is now standardized on RMS units, which is like steady average value, and UK might have rated audio gear in peak watts, which is approximately twice the RMS value. US manufacturers used to do it too, because the peak number is bigger. Now everybody pretty much talks in RMS units because everyone became wise to the peak-rating trick.

    In the 60's & early 70's, when the UK and the US were engaged in gear warfare, the term "British Rated Watts" was common. The rule of thumb was just take the British watts and multiply by 2 to get reasonably close to the US RMS equivalent.
