Speaker is excellent. Sound is amazing, very clear and it really plays everything (except sub bass). Sound is very powerful and you can surround anything, from small rooms up to very big halls. Sound is compatible with almost any subs under them, and with full power you can outvote 2 ETX18SP without any problem. They have SUB crossover so you can cut them whereever you want. In them you have so many options to adjust, from EQ up to mode how are you using them, it can be useful sometimes. They are little bit heavy but compared to almost any other 3-way speaker its nothing, for such a power they are easy.
I highly recommend buying this beast :D
