I agree with Viveks suggestion , eqlzr is a fine solution to control the treble and other tiny improvements....Contact our forum member rohitt he has a few eqlzrs....
Kiddy, if you don't mind my saying it, I think you are going about this in the wrong way.
At the outset you are getting confused between channel and frequency. A channel is a sort of pipe through which certain parts of the music or sound is sent. In stereo you have two channels, in 5.1 you have six, and in 7.1 you have eight.
All channels will carry a fully spectrum of frequencies excepting what is called the LFE. LFE is limited to carrying something like 250Hz and below and this can be adjusted through what is called a crossover.
What you are looking for is high treble and this is a frequency. Something like 6kHz and above. If you add a few tweeter and connect one 'channel' all you will get is distortion as the tweeter will a get a much higher range of frequencies than it can handle. Secondly you also would be cutting off the sound to a genuine speaker set that is set up to handle that channel.
The best way to handle this is through the AVR controls where you set up the frequency range of certain speakers. In some AVRs you also have a equalizer through which you can control what frequencies go to which speaker.
The second way to handle this is to get a pair of speakers that are brighter than what you have.
The third way is what has been suggested above. Use a graphic equalizer in your chain.
Directly connecting tweeter without managing the crossover properly is a very bad idea.

Hi Venkat,
You are absolutely right, I cannot just connect a pair of tweeters on any channel and solve my problem, it'll unbalance the sound I am getting.
In fact, my hardware setup what i mentioned in my previous one is lacking. note below
1) Onkyo 708
2) Sony BDP S 570( for blu ray viewing only)
3) Pioneer 1120 (for DVD and playing MP3s)
4) Iomega screenplay Director( for playing Audio, videos etc)
5) Sony NX500 LCD
All of the above are connected through HDMI.
My audio listening sources are different at diff times hence connecting a Eq in one of the source will not help me much.
My current setup is giving me enough of Hi Freq sound but I personally feel is not right though quality/clarity of sound through every components is exceptionally good I just need some extra punch on the treble when listening music.
i tried setting my Equalizers manually through setting on AVR, also tried Audissey.
Thnks for your suggestion once again.
Lets see if someone comes up with some bright idea.
