That is an excellent question. Some of this depends on your room and your preference. The cinema 10 have a very wide dispersion (meaning more of the seats will receive the same sound). This makes covering a large area better and also envelopes you more with sound. THe Cinema 6 on the other hand have a much narrower dispersion. THis is better for localization, ie telling where the sound is coming from the scene, but also won’t envelop you as much. This can be very beneficial for small rooms. Hopefully this helps.
