I have the JBL Eon 10G2's rated at 175 watts. I am wondering what kind of watts. Is that 175 watts RMS?

I don't know. I have the technical specs here but I can only read there's 125 watts low-frequency power and 50 watts high-frequency power. But there must be standing some values on the back panel of your system (there where you have the power supply). You need the value of the voltage (I guess 220 volts) and the value of the incoming current (I guess about 0.5 amps). So I would tend to say that 175 watts are the sinus power (peak-to-peak)...

Scott,
I think they write about RMS-power (longterm)when added both low- and high-amps.

Professional brands mostly use RMS-power handling rates.
What counts is continuous power with a max harmonic distortion of e.g. 0.03%

Hard to believe a hardware engineer is not aware of the fact that US mains-supplie is 120 Volts and the European is 230V nowadays

It is NOT OK to 'calculate' amplifier output power from the mains-input voltage and recommended amperage.

Peak-to-peak, peak or PMPO tell me nothing but are used to impress potential buyers without telling the harmonic distortion is > 10% !!

Perhaps http://www.aqdi.com/rms.htm can help ?

I'm sorry, but if the speaker causes the current to go ahead the voltage than maybe you should use a capacity in line to the speaker to eliminate this effect...
Isn't this a known fact out of Germany?

And it is a normal way to calculate the optional power inside through the incoming power of the power supply and (if you want to take it very exactly) the power which is blowing in the air...
How else would you know how many power your power amp will support?
Uh, yes , I forgot...if the manufacturer writes 250 watts RMS, then you'll know it...
And hey, you're absolutely right to say that the power is not the main thing but Scott had asked about that...

Oh, by the way, for me it makes not a big difference wether you use 220 volts or 230 volts (or sometimes 240 volts?). And also I remember a question by a member of this forum who lives in america. He'd asked about the power of his amp and it was switched to 230 volts by manufacturer. Is it possible that there are some states of america which are providing higher voltages than 110/120 volts? That would be very interesting for me...

In the example above I've written 0.5 amps at 220 volts. If you're using 110 volts than the current should be about 1.0 amps (based on the fact that 175 watts are not RMS but peak-to-peak). It's not good to make such cloudy specifications like RMS which nobody can really understand. We are musicians and music consumers we don't understand such terms like SPDIF, SMPTE, RMS, and so on...but nevertheless the manufacturers hold on to bombard us with such terms...

Scott,

JBL is a very reputable company. I'm sure the rating is rms output. Sheriff is confusing power consumed with output power. You cannot get rms output by calculating power consumed.

Sheriff as far as I know, all of the U.S. Canada and Mexico are on 120 volt 60 cycle power.

Tom

Okay, if the stated power really is RMS then the input values of the power supply must be a little different to that what I've written at first.

Tom, you're propably write! It's not easy for me to handle the term RMS as long as I don't know what this means in german. Maybe RMS means 'quadratischer Mittelwert'???

I only know that the output voltage of the secondary spoil have to be directed and smoothed/straighted. And at this point you habe to multiply the squareroot of '2' with this voltage to get the effective voltage. So this theoretically is your maximum output voltage. You really can't get more out of your device than this!!!
Then you need the value of your speaker (ohms and music output voltage of the power amp), the values of your power transistors and the value of your fuse resistor (collector multiplier). With these values you should be able to calculate your end-power.
Okay, if we go deeper in this thematic then we'll notice that there's some more to calculate. But for a short summary these values should be sufficient.
In earlier days those calculations resulted in terms like music power, sinus power and effective power. The effective power was that what really came out of the box. A few years ago a new terminology appeared in the scene - root means square!!!

In the case of JBL's Eon, what Scott was written about, I've got the technical specs as a PDF file. In this specs is written: 125 watts low-frequency and 50 watts high-frequency (bi-amplified) - actual power delivered to the drivers.

My guessing was that this is a two-way-system with separated values of effective powers which would give me more sense. Well, I guess this were just more than my 2 cents...maybe 5 cents?

Hey Scoot, the technical specs won't clear your question about the output power, I'm afraid. Also, I don't think that the power only isn't so important. If this system blasts you and/or your auditors away then it's quite good enough, isn't it?

Achtung Sheriff!

Actually, the typical comments are please turn it down........why does he play so loud. haha Also, turn down the bass!!(that's before I even started using the Logitech z5500 sub!

Tschuss........(sorry Sheriff, I think I really murdered the spelling on this one, which seems to me is used in Bavaria(Bayern)and Austria (Oesterreich)??

Okay, the word 'Tschüß' (or 'Tschuess' if the characters won't be shown correctly) has many different appearances. The base form is 'Tschüß' (Tschuess). In some parts of Germany you will hear 'Tschau'. Here in Frankfurt we say 'Atschö' (Atschoe) which let you feel the origin source of language - French!
It is the well known word 'adieu' or also known as 'adios' (in spain) and 'ciao' (in italy).

I think it is the most used greeting word all over the world after Hallo, Hello, Hola...

Another thing is your salutation to me because 'Achtung' means 'attention' and I don't like to be in school here...
