Number of speakers and watts Question

Discussion in 'Amps and Cabs [BG]' started by Wireking1, Jan 14, 2005.

  1. I am trying to determine how much power I am sending to each driver in my setup. I just want to be sure I don't fry my speakers.

    I have an ampeg 2x10 (8 ohms, rms 200) and 1x15 (8 ohms, 250 rms) beign powered by a QSC RMX-1450 bridged and running 1400 watts at 4 ohms.

    Just want to make sure I don't have WAY to much power for the speakers.

    You're hitting each cab with 700 watts peak. Which is pretty high for the rating of the speakers, but not a problem as long as you are very careful about clipping. If you hear distortion and/or see the clip light on the power amp blinking AT ALL, turn it down immediately.
  4. OK. I will watch it and not turn it up to much to be safe.

    At least I can get volume without coming close to clipping the amp now. Ladies and gentlemen, I am proud to announce that I have finally got some headroom for the first time!

    Thanks for the help.

    That ultimately depends on how high you run the volume control. Speakers don't generally die without first giving audible indications that they are stressed - except tweeters.
