NHT SuperZero vs Polk S10 vs HTM-200 SE vs RSL CG3

I have a small area to place speakers. With your help, I have narrowed it down to these four:

NHT SuperZero ($70 ea)

Polk S10 ($84 ea)

RSL CG3 ($135 ea)

Ascent HTM-200 SE ($163 ea)

These will be in a 2.1 configuration paired with a Denon AVR-540 in my living room. I have not purchased the sub yet. Mostly, these will be used for watching TV/movies. I am trying to not spend any more than necessary, so cost is a factor. However, if the added quality justifies the price increase, then I am happy to pay it.

haven't heard all your choices, but it's hard to go wrong with the superones--they're very big-sounding for such a little speaker and quite muscial
