Philips DS9800W/10 Fidelio SoundSphere... - Cross Talk

I was watching video, and correct me if i'm wrong but there was a mention of 'Cross Talk'. The person in the video was talking about cross talk between the drivers, where as the material I 'briefly' read up on dealt with cross talk in relationship with the speaker and the listener ... not between the drivers. So is this guy talking rubbish?
