Wireless speakers still need electrical power wat.t

If you are not too particular about SQ, have you test out those Yamaha Sound Bar system?

Basically a sound bar is a speaker system which consist of many small speakers at different angle. The concept is to use the wall to reflect the sound thus creating a surround sound effect. To be effective you need to have side wall for the sound to reflect. So bedroom is a good place to use sound bar. However, it's not good for living room whereby you only have 1 side wall while the other side is open. Hope this help.

Nobody used these sound bar, because everyone also know these system cannot really be a Hometheather system.

Friendly speaking, I dun thing the sound bar can produce the good sound sytem with sound reflect wall or even 'TIME DELAY'

Anyway, sound bar should be better than nothing, if u still prefer it, no need to ask, just buy a cheaper sound bar with HD system.

it'll be good if u indicate yr budget first. easier to suggest. else ... no end ler the poison .. ahahahahaha

Of cos there is a lot of premium brand selling Sound Bar, but my meaning is Sound Bar cannot perform like AVR + Separate speaker with 5.1/6.1/7.1 HD system, even you using the premium brand like B&W. I would say - Sound Bar is good for thoose are not so sensitive or demand in terms of sound quality  or effect, and just for thoose to have some sound effect / quality better than nothing(mean TV speaker).

For my opinion - If ur room really 2 small, I'll suggest you use satelite system (5.1). I think will Much Much better compare with Sound bar.

Anyway this is just my opinion. and here just for sharing.
