If I put them side ways will still work?
And also I have it in pair can I combine 2 of them side by side In the centre and use them as one speaker
This is the model Klipsch R41M 50-Watt Bookshelf Speaker

you can do anything you want as long as you mind the ohms and RMS of both the speaker(s) and amp.

E: hold it, thats self powered? all you need is the signal (assuming line level input), you're good to go.
E: never mind reading fail on the self powered.

wow. i guess no one has operated a line array . . . see those hanging huge speaker at concerts. all those tweeters and cones are parallel in the same cabinet. its Z depth of the drivers that matters unless you like the delay . .

don't worry about it. if you think it sounds like crap than turn it upright. simple. what you listen to and the surrounding environment (hard/soft surfaces) matters more.
