How do I set up a wireless speaker system in my apartment?
So I've got a desktop PC with wireless internet. I want to get speakers in my lounge/diner and in my bedroom that will play the music from my PC e.g. itunes/spotify.
Is it possible? Is it complicated?



Answer
You can buy wireless speakers which have a transmitter which plugs into e pc audio socket and receivers in the speakers.

Or you could buy a video sender, and ignore the picture part of it, plug the audio into the pc and plug some speakers Into the receiver end.

Or you could use Bluetooth, depending how far away the receiver needs to be (usually 10m or 30ft maximum). You can buy bluetooth speakers or an adapter (Belkin do one) that you can plug existing speakers into, If your PC doesn't have Bluetooth you can buy a USB Bluetooth adapter very cheaply.

On the other hand, all these are a bit expensive and diddly. It ought be easier to buy an iPod or other mp3 player and plug it into speakers in each room whe you need them.

I'm not sure that you'll be able to play to several sets of speakers at once whatever you do. Certainly not using Bluetooth.

What part of the power goes to the tweeters in a Speaker system?

I have a speaker system with a 12 inches, 4 ohms woofer and a 4 ohms piezoeletric tweeter.

My amplifer can give me 100 Watts RMS.

So, I need to know, how many of the power goes to the tweeter an how many goes tothe woofer?
But a 4.7 mF capacitor in series with the tweeter does not make it have another impedance different of 4 ohms?
4.7 mf = 4.7 microfarads, impossible write the "micro char" here.
I did not know RMS is a wromng term. But I already have read many magazines taht reffers to RMS as CONTINUOUS Watts.



Answer
If your amp puts out 100W then 100W can go to your tweeter if you put in a high frequency tone--of course you may not have a working tweeter after doing this.

Typical music has a spectrum such that 85% of the power is below 3kHz and 15% is above 3kHz. So according the website below you would have 15W to the tweeter...typically. If you read through the article you'll see it's a little more complex. Also, I've seen various shapes describing typical music, talk, etc. on other sites so your results will vary.
