My recollection of the Tiny Tots was that they were a location monitor made by Dave Wilson to monitor his recordings. They were described as (1) ruthlessly revealing with a somewhat rising treble, (2) difficult to drive (they went below 1 ohm at 2 Khz) and (3) severely lacking in bass (I think they cut off at about 50 Hz or so). One reviewer (John Atkinson) implied that they offered a vision of heaven but also a glimpse of hell, as I recall. Another said they desperately needed a woofer (much less a subwoofer), which is why when Wilson started marketing them seriously, they designed the Puppy woofers to go with them. Before that I recall a lot of people paired them with Entec subwoofers, which doubled as a stand for them (that's how I heard them years ago).
I think it will be difficult to get the best out of them from a receiver, but if you can get one that can drive very low impedance loads, I suppose it could work for a HT system. I think Audiotroy is right, though, they will work best with a quality integrated. In any case, if you just want the Wilsons for dialogue from movies it would be OK and probably better than a soundbar, but I doubt that you'll get much bass from the soundtracks without at least a decent subwoofer crossed over in the mid-bass region.
Just my two cents, but if you check the Stereophile archives I think you'll get a good idea of the strengths and weaknesses of the speaker.
