Top notch speakers with their own sub

I have a pair of Infinity Prelude MTS complete with subs and towers. They serve me very well, don't require too much power because they have their own powered subs. The multiple components for upper base and mid range do have their advantage, giving a rather complete sound projection. This pair of Class A speakers certain have lived up to their pedigree, but the technology is about 10 years old. What would recommend for the current technology? I am looking for a pair of full size speakers that have their own powered sub.
