you need to specify your price range. There are many stand mount speakers that fit your descripton, but many are quite expensive. think Harbeth, Spendor, Sonus Faber. An advantage of stand mount is that less money is spent on the speaker box and there is less box material to resonate and muddy the sound. But you still have to buy stands, so figure that into your equation. Also, subwoofer integration with small monitor speakers isnt as easy as just connecting and play. Most people over do the level of the sub, and run it too high in frequency. If you are just trying to fill in the bass, then your crossover shouldnt be any higher than 80hz max, preferrably 60hz. then play some bass heavy music and turn up the sub until you just notice it, then back off a hair. thats a good starting place.
a well designed 3 way will likely sound better than a sub/satellite system, but not always
