Standard (8 or 10 speakers), Soundpack (seperate amp under the pass seat) and certain ones have DynAudio, which is like the bose kit on an audi (again amped under the seat).
RNS 510 should have the 10 speaker pack as standard giving you seperate woofer mid and treb in each front door, and a woofer/mid and treb in the rear doors
Sound is reasonable out of them, but I still had to add a sub to get a more balanced sound ;)
