It will be used for music, that's all.
the sources may be my amplifier itself, as it have a pen drive reader and can play songs from it and LED TV.
i will use it in my living room, its size might be 12*16 feet approx.
I have an amplifier of 20w RMS output and 4ohm impedance, it is stereo amplifier,
