If you are juryrigging more, you seem to be on your own. Even the hub http://www.samsung.com/us/video/home-audio/WAM250/ZA does not seem to go beyond 2 channels.
To get 5.1 you might jury rig it by using a receiver and wire it up but it looks easier to go with the classic receiver and speakers.
HI. What surround options are there for these speakers when connected to a hub in the same room? For example, if u have 2 of these speakers u can connect it as stereo. If u have 3 of these speakers u can connect it as left, right and centre channel. If u have of 4 these speakers, can u connect it as 4 channel stereo? I know 5 speakers gives u the typical home theatre surround 5.1 setup. So if u have 4 of these speakers, can it be configured as 4 channel stereo?
