No beauce there is only a single speaker but you can mess with the eq to see if you find one that sounds better to you but won't really fix right left.
Ok with headphones you would have a left and a right but the only options you have is mono or stereo. Now if you need for just certain things than I would say go and make the audio playback more to the left or right. This would be required for everything unless it is just certain files. Really no way around it with just the iPad.
