Hi everyone. I'm a new member of the group
I have a few questions that I hope folk here can help me with.
I'm now in my 60's (OLD) but have been involved in audio since my early teens...
I remember when an amplifier rated at 100watts RMS per channel (stereo) into 8ohm speakers was considered extremely loud, and in fact mine brought many a rude comment from neighbours up and down the entire street!
Now I see units rated at 1000watts are for sale in many and various shops for so cheap it's,well, unbelievable
These ratings by the way are in watts RMS NOT peak power output or some other weird computation.
I recently went to a audio store to listen to one of these units..1100 watts RMS it boldly stated. Five speakers apparently handled this RMS output, I guess dividing the power between them with possibly electronic crossovers.
I mentioned to the salesman that I was used of listening to 200watts max and was told that "these days" that amount of power would not be loud enough in any "normal" house.
Upon turning up the volume to its sad distorting max I mentioned that if the unit was outputting 50 watts RMS I would be surprised indeed.
So, may I humbly ask you here: Has the term RMS been re-rated ?
Wattage RMS can be easily calculated by squaring the voltage across the speaker terminals and dividing it by the speaker impedance. Thus with an oscilloscope or RMS meter, a audio signal generator/ white/pink noise generator, it is quite possible to measure the output in RMS before distortion begins.
But how is "RMS" power output measured these days ?
Are these units really delivering there advertised output and it's my poor aged ears that are the problem?
Does the term RMS still have any valid meaning ?
If it does, how do these guys get away with such lies when there is supposed to be truth in advertising legislation ?
Is it just that we have become so slack/ ignorant or accepting of these claims that we don't care anymore.
It's really quite sad to me.
Cheers to all.
