What is lacking with your 802D? Also what amps are you using?
I think 802D are pretty good all around speaker. But you can find better speakers. You also do not need to break the bank to do so. There are many speakers in the 802D price-range with different sounds you might like better. Just because you spend $25,000 on speakers does not mean you will like them better than your $14,000 802Ds....
