The differences that exist are so subtle, an A/B comparison is virtually required to distinguish a difference.

The 80s do play a deeper range of bass so it is a bit more prominent and because of the extra drivers and cabinet size, it can play louder, better suited to even larger rooms.

Both speakers are excellent and VERY close in sound. Base your decision on room size and/or preference for extended bass (assuming you are not relying on a subwoofer for the low end).
