another thing to consider is watts rms at what percent total harmonic distortion.
A guitar amp might be 50 watts @5%THD, A good stero amp is, lets say 100 watts @ .01% THD. A way to boost the ratings is to take the 100w@.01%THD and call it 300 watts and not tell you that it is 300w@2%THD. The numbers are made up just to give you an example, the lower the THD the cleaner the amp is and the more useable power.

Watts RMS can apply to amps or to speakers. If an amp is described as '50 watts RMS' it refers to the power of the amp. If a speaker is described as '50 watts RMS' it refers to the power the speaker is designed to accept. If a set of powered speakers is described as '50 watts RMS' it refers to both the amp and speakers.

Whether or not the amp is separate from the speakers is found elsewhere.

Thanks for the info, Im sending my cab out tomorrow, and ordering the Phillips Gemini GSM1580. It looks perfect, and decent ratings. Ill try it out, and see how it goes!

Thanks,

Phil

That doesn't sound like a powered speaker.
