AV Receiver To Powerful For Speakers?

[Coops_THC]

Hi,

Let me start off by saying i am new to this. This is my first home theatre setup. I have never owned/used a AV Receiver in my life.

I have my mind pretty set on getting the Pioneer VSX922 as reviews are pretty awesome and i can get it for £199.

I am have a little trouble finding a speaker package to go with it. I am on a tight budget and my living room is small so floor standers are out of the question.

I have seen these little guys, Boston Acoustics Soundware XS SE 5.1, which i think would be a great start and i can upgrade as and when i can afford but i am not sure if they will work together. "The Recommended Amplifier Power Range" for the satellite speakers is 10-100 watts however the power output per channel on the receiver is 150/105w (Not sure which as i will explain) Will this damage the speakers?

I am unsure what wattage the speaker output is because i have taken a look at the specifications which states 2 different values.

Any help on the above would be much appreciated.

I shouldn't worry about this.

The speakers are specified as an 8ohm load and can handle 100 watts of power.

The Pioneer will produce 105Watts into such an 8 ohm load, if run absolutely flat out.

105 Watts is equivalent to 20 dBW, add this to the sensitivity of the speakers which

is specified as giving an output of 85dB for 1 watt input

So if you were to listen with the volume control at max, then the 5 speakers

combined would be producing a Sound Pressure Level well over 105dB, this would be unbearable

and according to various authorities such as http://www.noisehelp.com/noise-dose.html

http://www.gcaudio.com/resources/howtos/loudness.html

could result in hearing loss if exposed to this level for less than 10 minutes per day.

If you listen at normal sensible less than 90dB'ish levels then most of the time the Pioneer will be coasting along

at less than 5W, occasionally putting out more for the occasional loud musical/movie moment.

Your ears will give in before the loudspeakers

Thanks a lot. I will get these purchased.
